This patch stores existence of the image in the object. At start of the daemon the state is checked and then updated in key moments in domain lifecycle.

This patch wires up the RPC protocol handlers for virConnectListAllDomains(). The RPC generator has no support for the way how virConnectListAllDomains() returns the results so the handler code had to be done manually. The new api is handled by REMOTE_PROC_CONNECT_LIST_ALL_DOMAINS, with number 273 and marked with high priority.

This patch adds a new public api that lists domains. The new approach is different from those used before. There are key points to this: 1) The list is acquired atomically and contains both active and inactive domains (guests). This eliminates the need to call two different list APIs, where the state might change in between the calls. 2) The returned list consists of virDomainPtrs instead of names or ID's that have to be converted to virDomainPtrs anyways using separate calls for each one of them. This is more convenient and saves hypervisor calls. 3) The returned list is auto-allocated. This saves a lot of hassle for the users. 4) Built in support for filtering. The API call supports various filtering flags that modify the output list according to user needs. Available filter groups: Domain status: VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE Domain persistence: VIR_CONNECT_LIST_DOMAINS_PERSISTENT, VIR_CONNECT_LIST_DOMAINS_TRANSIENT Domain state: VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED, VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER Existence of managed save image: VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE, VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE Auto-start option: VIR_CONNECT_LIST_DOMAINS_AUTOSTART, VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART Existence of snapshot: VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT, VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT 5) The python binding returns a list of domain objects that is very neat to work with. The only problem with this approach is no support from code generators so both RPC code and python bindings had to be written manually. *include/libvirt/libvirt.h.in: - add API prototype - clean up whitespace mistakes nearby *python/generator.py: - inhibit generation of the bindings for the new api *src/driver.h: - add driver prototype - clean up some whitespace mistakes nearby *src/libvirt.c: - add public implementation *src/libvirt_public.syms: - export the new symbol

Commit 6e769eba made it a runtime error if libvirt was compiled without yajl support but targets a new enough qemu. But enough users are hitting this on self-compiled libvirt that it is worth erroring out at compilation time, rather than an obscure failure when trying to use the built executable. * configure.ac: If qemu is requested and -version works, require yajl when qemu version is new enough. * src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Add comment.

dump-guest-memory is a new dump mechanism, and it can work when the guest uses host devices. This patch adds a API to use this new monitor command. We will always use json mode if qemu's version is >= 0.15, so I don't implement the API for text mode.

This reverts commit c16b4c43 Author: Daniel P. Berrange <berrange@redhat.com> Date: Fri May 11 15:09:27 2012 +0100 Avoid LXC pivot root in the root source is still / This commit broke setup of /dev, because the code which deals with setting up a private /dev and /dev/pts only works if you do a pivotroot. The original intent of avoiding the pivot root was to try and ensure the new root has a minimumal mount tree. The better way todo this is to just unmount the bits we don't want (ie old /proc & /sys subtrees. So apply the logic from commit c529b47a Author: Daniel P.

Libvirt updates the configuration of SPICE server only when something changes. This is unfortunate when the user wants to disconnect a existing spice session when the connected attribute is already "disconnect". This patch modifies the conditions for calling the password updater to be called when nothing changes, but the connected attribute is already "disconnect".

While unescaping the commands the commands passed through to the monitor function qemuMonitorUnescapeArg() initialized lenght of the input string to strlen()+1 which is fine for alloc but not for iteration of the string. This patch fixes the off-by-one error and drops the pointless check for a single trailing slash that is automaticaly handled by the default branch of switch.

commit 52d064f4 added VIR_NETWORK_XML_INACTIVE in order to allow suppressing the auto-generated list of VFs in network definitions, and a --inactive flag to virsh net-dumpxml to take advantage of the flag. However, it missed out on two opportunities: 1) Use INACTIVE to get the current config of the network as it exists on disk, rather than the currently active config. 2) Add INACTIVE to the flags used for the virsh net-edit command, so that it won't include the forward-pool interfaces that were autogenerated, and so that a re-edit of the network prior to restarting it will show any other edits made since the last restart of the network. (prior to this patch, if you edited a network a 2nd time without restarting, all of the previous edits would magically disappear). In order to fit with the new #define-based generic edit function in virsh.c, a new function vshNetworkGetXMLDesc() was added. This function first tries to call virNetworkGetXMLDesc with the INACTIVE flag added, then retries without if the first attempt fails (in the manner expected when the server doesn't support it).

A core use case of the hook scripts is to be able to do things to a guest's network configuration. It is possible to hook into the 'start' operation for a QEMU guest which runs just before the guest is started. The TAP devices will exist at this point, but the QEMU process will not. It can be desirable to have a 'started' hook too, which runs once QEMU has started. If libvirtd is restarted it will re-populate firewall rules, but there is no QEMU hook to trigger for existing domains. This is solved with a 'reconnect' hook. Finally, if attaching to an external QEMU process there needs to be an 'attach' hook script. This all also applies to the LXC driver * docs/hooks.html.in: Document new operations * src/util/hooks.c, src/util/hooks.c: Add 'started', 'reconnect' and 'attach' operations for QEMU.

First 'poll' can't return EWOULDBLOCK, and second, we're checking errno so far away from the poll() call that we've probably already trashed the original errno value.

In addition to keepalive responses, we also need to send keepalive requests from client IO loop to properly detect dead connection in case a libvirt API is called from the main loop, which prevents any timers to be called.

We don't need to add or remove filters when client object is already locked anymore. There's no reason to keep the *Locked variants of those APIs.

The previous commit removed the only usage of ``all'' parameter in virKeepAliveStopInternal, which was actually the only reason for having virKeepAliveStopInternal. This effectively reverts most of commit 6446a9e2.
-
由 Jiri Denemark 提交于
When a libvirt API is called from the main event loop (which seems to be common in event-based glib apps), the client IO loop would properly handle keepalive requests sent by a server but will not actually send them because the main event loop is blocked with the API. This patch gets rid of response timer and the thread which is processing keepalive requests is also responsible for queueing responses for delivery.

Add virKeepAliveTimeout and virKeepAliveTrigger APIs that can be used to set poll timeouts and trigger keepalive timer. virKeepAliveTrigger checks if it is called to early and does nothing in that case.
-
由 Jiri Denemark 提交于
The code that needs to be run every keepalive interval of inactivity was only called from a timer and thus from the main event loop. We will need to call the code directly from another place.

As we never drop non-blocking calls, the return value that used to indicate a call was dropped is no longer needed.
-
由 Jiri Denemark 提交于
As non-blocking calls are no longer dropped, we don't really need to care that much about their fate and wait for the thread with the buck to process them. If another thread has the buck, we can just push a non-blocking call to the queue and be done with it.
-
由 Jiri Denemark 提交于
So far, we were dropping non-blocking calls whenever sending them would block. In case a client is sending lots of stream calls (which are not supposed to generate any reply), the assumption that having other calls in a queue is sufficient to get a reply from the server doesn't work. I tried to fix this in b1e374a7 but failed and reverted that commit. With this patch, non-blocking calls are never dropped (unless the connection is being closed) and will always be sent.
-
由 Jiri Denemark 提交于
Normally, when every call has a thread associated with it, the thread may get the buck and be in charge of sending all calls until its own call is done. When we introduced non-blocking calls, we had to add special handling of new non-blocking calls. This patch uses event loop to send data if there is no thread to get the buck so that any non-blocking calls left in the queue are properly sent without having to handle them specially. It also avoids adding even more cruft to client IO loop in the following patches. With this change in, non-blocking calls may see unpredictable delays in delivery when the client has no event loop registered. However, the only non-blocking calls we have are keepalives and we already require event loop for them, which makes this a non-issue until someone introduces new non-blocking calls.

'make dist' was depending on *protocol-structs files, which are stored in git but in turn depended on generated files. We still want to ship the protocol-structs files, but by renaming the tests to something not matching a file name, we separate 'make check' (which depends on the generated file) from 'make dist' (which only depends on the git files). After all, the tarball should never depend on a generated file not stored in git. I found one more case of a git file depending on a generated file, in a bogus virkeycode.c listing; but at least this one had no associated rules so it never broke 'make dist'. Reported by Wen Congyang. Latent bug has been present since commit 62dee6fa, but only recently exposed by commit 7bff56a0. * src/Makefile.am ($(srcdir)/util/virkeycode.c): Drop useless dependency. (BUILT_SOURCES): ...and build virkeymaps.h sooner. (PROTOCOL_STRUCTS): Rather than depend on the struct file... (check-local): ...convert things into a phony target of... (check-protocol): ...a new check. ($(srcdir)/remote_protocol-struct): Rename to isolate the distributed file from the conditional test. (PDWTAGS): Deal with rename. Swap to compare 'expected actual'.
