This patch adds infrastructure and command line option for setting global defaults for device properties, i.e. you can for example use -global virtio-blk-pci.vectors=0 to turn off msi by default for all virtio block devices. The config file syntax is: [global] driver = "virtio-blk-pci" property = "vectors" value = "0" This can also be used to set properties for devices which are not created via -device but implicitly via machine init, i.e. -global isa-fdc,driveA=<name> This patch uses the mechanism which configures properties for the compatibility machine types (pc-0.10 & friends). The command line takes precedence over the machine type values. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This commit adds a flag called 'control' to the '-monitor' command-line option. This flag enables control mode. The syntax is: qemu [...] -monitor control,<device> Where <device> is a chardev (excluding 'vc', for obvious reasons). For example: $ qemu [...] -monitor control,tcp:localhost:4444,server Will run QEMU in control mode, waiting for a client TCP connection on localhost port 4444. NOTE: I've tried using QemuOpts for this, but turns out that it will try to parse the device part, which should be untouched.

Adds -readconfig and -writeconfig command line switches to read/write QemuOpts from config file. In theory you should be able to do: qemu < machine config cmd line switches here > -writeconfig vm.cfg qemu -readconfig vm.cfg In practice it will not work. Not all command line switches are converted to QemuOpts, so you'll have to keep the not-yet converted ones on the second line. Also there might be bugs lurking which prevent even the converted ones from working correctly. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Switch RTC emulations to the new host_clock instead of vm_clock by default. This has the advantage that the emulated RTC will follow automatically the host time while it might be tuned via NTP. vm_clock can still be selected by passing '-rtc clock=vm' on the command line. Note that some RTC emulations (at least M48T59) already use the host time unconditionally while others (namely MC146818) do not. This patch introduces the required infrastructure for selecting the base clock but only converts MC146818 for now.

start switching chardevs to QemuOpts. This patch adds the infrastructure and converts the null device. The patch brings two new functions: qemu_chr_open_opts() same as qemu_chr_open(), but uses QemuOpts instead of a option char string. qemu_chr_parse_compat() accepts a traditional chardev option string, returns the corresponding QemuOpts instance, to handle backward compatibility. The patch also adds a new -chardev switch which can be used to create named+unconnected chardevs, like this: -chardev null,id=test This uses the new qemu_chr_open_opts. Thus with this patch alone only the null device works. The other devices will follow ... Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Now that do have a nicer interface to work against we can add Linux native AIO support. It's an extremly thing layer just setting up an iocb for the io_submit system call in the submission path, and registering an eventfd with the qemu poll handler to do complete the iocbs directly from there. This started out based on Anthony's earlier AIO patch, but after estimated 42,000 rewrites and just as many build system changes there's not much left of it. To enable native kernel aio use the aio=native sub-command on the drive command line. I have also added an option to qemu-io to test the aio support without needing a guest.

The ne2k is an ancient card that performs pretty terribly under QEMU. In many modern OSes, there is no longer drivers available for the ne2k. Switch the default network adapter to e1000. This card is more widely suppported and performs rather well under QEMU. There may be very old OSes that had a ne2k driver but not an e1000 driver but I think this is likely the exception. I think the average user is better served with an e1000 vs ne2k. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

On reflection, perhaps it does make sense to set a default value for the sndbuf= tap parameter. For best effect, sndbuf= should be set to just below the capacity of the physical NIC. Setting it higher will cause packets to be dropped before the limit is hit. Setting it much lower will not cause any problems unless you set it low enough such that the guest cannot queue up new packets before the NIC has emptied its queue. In Linux, txqueuelen=1000 by default for ethernet NICs. Given a 1500 byte MTU, 1Mb is a good choice for sndbuf. If it turns out that txqueuelen is actually much lower than this, then sndbuf is essentially disabled. In the event that txqueuelen is much higher, it's unlikely that the NIC will be able to empty a 1Mb queue. Thanks to Herbert Xu for this logic.

With the internal IP configuration made more flexible, we can now enhance the user interface. This patch adds a number of new options to "-net user": net (address and mask), host, dhcpstart, dns and smbserver. It also renames "redir" to "hostfwd" and "channel" to "guestfwd" in order to (hopefully) clarify their meanings. The format of guestfwd is extended so that the user can define not only the port but also the virtual server's IP address the forwarding starts from.

So far a couple of slirp-related parameters were expressed via stand-alone command line options. This it inconsistent and unintuitive. Moreover, it prevents both dynamically reconfigured (host_net_add/ delete) and multi-instance slirp. This patch refactors the configuration by turning -smb, -redir, -tftp and -bootp as well as -net channel into options of "-net user". The old stand-alone command line options are still processed, but no longer advertised. This allows smooth migration of management applications to to the new syntax and also the extension of that syntax later in this series.

2.6.30 adds a new TUNSETSNDBUF ioctl() which allows a send buffer limit for the tap device to be specified. When this limit is reached, a tap write() will return EAGAIN and poll() will indicate the fd isn't writable. This allows people to tune their setups so as to avoid e.g. UDP packet loss when the sending application in the guest out-runs the NIC in the host. There is no obviously sensible default setting - a suitable value depends mostly on the capabilities of the physical NIC through which the packets are being sent. Also, note that when using a bridge with netfilter enabled, we currently never get EAGAIN because netfilter causes the packet to be immediately orphaned. Set /proc/sys/net/bridge/bridge nf-call-iptables to zero to disable this behaviour. Signed-off-by: NMark McLoughlin <markmc@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
