[libvirt] [PATCH 0/5] Explicit boot device ordering
by Jiri Denemark
Currently, boot order can be specified per device class but there is no
way to specify exact disk/NIC device to boot from. This patchset fixes
that.
There were two options suggested for how this should be modeled in
domain XML:
1)
<os>
<boot target='net1'/>
<boot target='net0'/>
<boot target='hdc'/>
<boot target='hdb'/>
<os>
Where target attributes would match /domain/devices/*/target@dev
2) Adding <boot order='n'/> elements into appropriate device elements.
In addition to the two options Rich suggested a more compact variant of
option 1.
Per former discussion this patchset implements the second option.
Jiri Denemark (5):
conf: Move boot parsing into a separate function
Introduce per-device boot element
qemu: Refactor qemuCapsParsePCIDeviceStrs using virCommand
qemu: Support per-device boot ordering
tests: Add tests for per-device boot elements

[libvirt] [Patch v5 0/4] Add new feature into live migration
by Wen Congyang
If the memory of guest OS is changed constantly, the live migration
can not be ended ever for ever.
We can use the command 'virsh migrate-setmaxdowntime' to control the
live migration. But the value of maxdowntime is diffcult to calculate
because it depends on the transfer speed of network and constantly
changing memroy size. We need a easy way to control the live migration.
This patch set add the support of forcing guest to suspend at timeout.
With this patch set, when we migrate the guest OS, we can specify a
timeout. If the live migration timeouts, auto-suspend the guest OS,
where the migration will complete offline.
Test of this patchset on Linux:
Env:
a. The size of guest OS's memory: 1GB
b. The transfer speed of network: about 100Mb/s
c. The size of constantly changing memory: more than 900MB
1. migrate without timeout
# virsh migrate --live RHEL6RC qemu+ssh://<dest IP>/system tcp://<dest IP>:49152
The migration does not end after 12 hours.
2. migrate with timeout(30 minutes):
# virsh -t migrate --live --timeout 1800 RHEL6RC qemu+ssh://<dest IP>/system tcp:<dest IP>:49152
(Time: 1816768.066 ms)
v5:
- merge daemon/event.* and src/util/event.*
- test event when builing without libvirtd
v4:
- move tools/timer.* into src/util/ directory
v3:
- use the existing virEventXXXTimeout() APT to implement timer
- merge Add, Update, Delete into one single interface virSetTimeout()
- start timer thread when initializing timer
v2:
- implement timer for Windows
- implement dynamic timers

[libvirt] [PATCH] build: restore mingw build
by Eric Blake
* bootstrap.conf (gnulib_modules): Add chmod.
---
Pushing under the build-breaker rule; ./autobuild.sh failed to
cross-compile to mingw due to commit d596c6d requiring chown().
The gnulib function is just an always-failing stub on mingw,
but at least it lets things link again.

[libvirt] [v3] qemu: Reject SDL graphic if it's not supported by qemu
by Osier Yang
If the emulator doesn't support SDL graphic, we should reject
the use of SDL graphic xml with error messages, but not ignore
it silently, and pretend things are fine.
"-sdl" flag was exposed explicitly by qemu since 0.10.0, more detail:
http://www.redhat.com/archives/libvir-list/2011-January/msg00442.html
And we already have capability flag "QEMUD_CMD_FLAG_0_10", which
could be used to prevent the patch affecting the older versions
of QEMU.

[libvirt] [Patch v2 0/2] Some fixes about p2p migration
by Wen Congyang
When we migrate a guest from remote host to localhost by p2p, the libvirtd
on remote host will be deadlock. This patch fixes a bug and we can avoid
the deadlock with this patch.
The steps to reproduce this bug:
# virsh -c qemu+ssh://<remotehost IP>/system migrate --p2p <domain name> qemu+ssh:///system
v2:
- report error instead of changing the desturi as Daniel suggested
- improve the documentation of desturi
Wen Congyang (2):
report error when specifying wrong desturi

[libvirt] openvzReadNetworkConf:318 : out of memory

I have been working to get libvirt to work with openvz and kvm. I have had
no issues with KVM but libvirt is hit or miss. Sometimes I get it to work,
but most of the time I get back "out of memory". I have tried all recent
versions of libvirt and vzctl from openvz. Any pointers?

[libvirt] [v2] qemu: Reject SDL graphic if it's not supported by qemu
by Osier Yang
If the emulator doesn't support SDL graphic, we should reject
the use of SDL graphic xml with error messages, but not ignore
it silently, and pretend things are fine.
"-sdl" flag was exposed explicitly by qemu since 0.10.0, more detail:
http://www.redhat.com/archives/libvir-list/2011-January/msg00442.html
And we already have capability flag "QEMUD_CMD_FLAG_0_10", which
could be used to prevent the patch affecting the older versions
of QEMU.
