Despite the fact that the qemu-tool environment has no guest running and vm_clock therefore does not make sense, there is code that gets the vm_clock time even in qemu-tool. Therefore, revert the abort(3) call and just return 0 like we used to. This unbreaks qemu-img/qemu-io with QED and Kevin has also expressed interest in this for qcow2.

Block layer tests that involve QMP commands rather than qemu-img or qemu-io are not well-suited for shell scripting. This patch adds a Python module which allows tests to be written in Python instead. The basic API is: VM - class for launching and interacting with a VM QMPTestCase - abstract base class for tests that use QMP qemu_img() - wrapper function for invoking qemu-img qemu_io() - wrapper function for invoking qemu-io imgfmt - the image format under test (e.g. qcow2, qed) test_dir - scratch directory path for temporary files main() - entry point for running tests Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This adds the QMP command for blockdev-group-snapshot-sync. It takes an array in as the input, for the argument devlist. The array consists of the following elements: + device: device to snapshot. e.g. "ide-hd0", "virtio0" + snapshot-file: path & file for the snapshot image. e.g. "/tmp/file.img" + format: snapshot format. e.g., "qcow2". Optional There is no HMP equivalent for the command. Signed-off-by: NJeff Cody <jcody@redhat.com> Acked-by: NLuiz Capitulino <lcapitulino@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

由 Jeff Cody 提交于
This is a QAPI/QMP only command to take a snapshot of a group of devices. This is similar to the blockdev-snapshot-sync command, except blockdev-group-snapshot-sync accepts a list devices, filenames, and formats. It is attempted to keep the snapshot of the group atomic; if the creation or open of any of the new snapshots fails, then all of the new snapshots are abandoned, and the name of the snapshot image that failed is returned. The failure case should not interrupt any operations. Rather than use bdrv_close() along with a subsequent bdrv_open() to perform the pivot, the original image is never closed and the new image is placed 'in front' of the original image via manipulation of the BlockDriverState fields. Thus, once the new snapshot image has been successfully created, there are no more failure points before pivoting to the new snapshot. This allows the group of disks to remain consistent with each other, even across snapshot failures.

The spec says that the length of extensions is padded to 8 bytes, not the offset. Currently this is the same because the header size is a multiple of 8, so this is only about compatibility with future changes to the header size. While touching it, move the calculation to a common place instead of duplicating it for each header extension type.

Floppies can be simple or double-sided. However, current code was only taking the common case into account (ie 2 sides). This repairs single-sided floppies, which where totally broken before this patch : for track > 0, wrong sector number was calculated, and data was read/written at wrong place on underlying device. Fortunately, only some 360 kB floppies are single-sided, so this bug was probably not seen much. Signed-off-by: NHervé Poussineau <hpoussin@reactos.org> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds an 64bit pci bar for vram. It is turned off by default. It can be enabled by setting the size of the 64bit bar to be larger than the 32bit bar. Both 32bit and 64bit bar refer to the same memory. Only the first part of the memory is available via 32bit bar. The intention is to allow large vram sizes for 64bit guests, by allowing the vram bar being mapped above 4G, so we don't have to squeeze it into the pci I/O window below 4G. With vram_size_mb=16 and vram64_size_mb=256 it looks like this: 00:02.0 VGA compatible controller: Red Hat, Inc.

When creating an USB device the old way, there is no way to specify the target bus. Thus the warning issued by usb_create makes no sense and rather confuses our users.

The guest network stack might DHCPREQUEST an address that the slirp built in dhcp server can't let it have - for example if the guest has an old leases file from another network configuration. In this case the dhcp server should and does reject the request and prepares to send a DHCPNAK to the client. However, in this case the daddr variable in bootp_reply() is set to 0.0.0.0. Shortly afterwards, it unconditionally attempts to pre-insert the new client address into the ARP table. This causes an assertion failure in arp_address_add() because of the 0.0.0.0 address. According to RFC2131, DHCPNAK messages for clients on the same subnet must be sent to the broadcast address (S3.2, subpoint 2).

In case we requeued a packet that was the head of a longer session queue, we failed to restore this ordering. Also, we did not properly deal with changes to Slirp::next_m. Instead of a cumbersome roll back, this fix simply avoids any changes until we know if the packet was actually sent. Both fixes crashes due to inconsistent queues and simplifies the logic.
