[libvirt] [PATCH 00/14] Add support for XBZRLE migration compression
by Jiri Denemark
QEMU supports XBZRLE compression of repeatedly transferred pages during
live migration and this series makes it usable through libvirt. The first
two patches add support for VIR_MIGRATE_COMPRESSED flag that enables
XBZRLE compression. Patches 3--9 add an enhanced and extensible version
of virDomainGetJobInfo and make various migration statistics available
through it. The rest of the patches (10--14) add APIs for querying and
changing XBZRLE compression cache size.
Jiri Denemark (14):
Introduce VIR_MIGRATE_COMPRESSED flag
qemu: Add support for compressed migration
Introduce virDomainGetJobStats API
python: Implement virDomainGetJobStats wrapper
remote: Auto-allocate params in remoteDeserializeTypedParameters
remote: Implement virDomainGetJobStats
virsh: Use virDomainGetJobStats in domjobinfo if available
qemu: Parse more fields from query-migrate QMP command
qemu: Implement virDomainGetJobStats
Introduce virDomainMigrate*CompressionCache APIs
python: Implement virDomainMigrateGetCompressionCache wrapper
remote: Implement virDomainMigrate*CompressionCache
virsh: Add migrate-compcache command
qemu: Implement virDomainMigrate*CompressionCache

[libvirt] [PATCH 0/2] qemu: allow multiple buses in PCI address allocation
by Ján Tomko
This miniseries converts the functions for reserving PCI addresses
to use virDevicePCIAddress which we use in virDeviceInfo for PCI addresses
(not to be confused with virPCIDeviceAddress from virpci.h used for host
devices which should probably be merged with virDevicePCIAddress in a followup
patch) and it makes them accept bus numbers up to 'maxbus', which should be set
when creating the address set if multiple buses are allowed.
Right now it's initialized to zero and these patches have no effect.
Ján Tomko (2):
qemu: switch PCI address alocation to use virDevicePCIAddress
qemu: allow multiple buses in PCI address alocation

[libvirt] How to connect to console of domain on PowerPC?
by Yin Olivia-R63875
Hi,
I tried to use libvirt to run KVM/QEMU on Freescale PowerPC platforms.
So far there's only one serial device (spapr-vty) defined in QEMU to work as console for IBM PSeries platform.
There's no serial device support in QEMU for Freescale PowerPC (ePAPR).
libvirt/src/qemu/qemu_command.c
/* This function generates the correct '-device' string for character
* devices of each architecture.
*/
char *
qemuBuildChrDeviceStr(virDomainChrDefPtr serial,
virBitmapPtr qemuCaps,
char *os_arch,
char *machine)
{
virBuffer cmd = VIR_BUFFER_INITIALIZER;
if (STREQ(os_arch, "ppc64") && STREQ(machine, "pseries")) {
if (serial->deviceType == VIR_DOMAIN_CHR_DEVICE_TYPE_SERIAL &&
serial->source.type == VIR_DOMAIN_CHR_TYPE_PTY &&
serial->info.type == VIR_DOMAIN_DEVICE_ADDRESS_TYPE_SPAPRVIO) {
virBufferAsprintf(&cmd, "spapr-vty,chardev=char%s",
serial->info.alias);
if (qemuBuildDeviceAddressStr(&cmd, &serial->info, qemuCaps) < 0)
goto error;
}
} else
virBufferAsprintf(&cmd, "isa-serial,chardev=char%s,id=%s",
serial->info.alias, serial->info.alias);
if (virBufferError(&cmd)) {
virReportOOMError();
goto error;
}
return virBufferContentAndReset(&cmd);
error:
virBufferFreeAndReset(&cmd);
return NULL;
}
We usually connect guest with telnet.
For instance,
/usr/bin/qemu-system-ppc -name demo -M ppce500v2 -enable-kvm -m 256 -nographic -kernel /media/ram/uImage -initrd /media/ram/ramdisk -append "root=/dev/ram rw console=ttyS0,115200" -serial tcp::4445,server
Then to run 'telnet 10.193.20.xxx 4445' could connect the guest.
The temporary workaround is not add '-device' string after '-serial' option.

Then there's no other output after the below message:

It seemed not libvirt group issue.
I also tried the LXC.
It could connect to the console if <init>/bin/sh/</init> instead of <init>/sbin/init</init>

[libvirt] [PATCHv2 0/6] interface: udev backend bond support
by Doug Goldstein
Refactor code, clean up error handling, and finally add bond support. The
last patch optionally supports a patch I submitted to the Linux kernel
which should go in for 3.9 (it was just accepted for net-next).
After this patch when you have a bond device you'll get the following:
$ ./tools/virsh iface-dumpxml br0
<interface type='bridge' name='br0'>
<mtu size='1500'/>
<bridge stp='on' delay='1499'>
<interface type='bond' name='bond0'>
<mtu size='1500'/>
<bond mode='balance-rr'>
<interface type='ethernet' name='eth2'>
<mac address='d0:67:e5:fa:88:95'/>
<mtu size='1500'/>
</interface>
<interface type='ethernet' name='eth3'>
<mac address='d0:67:e5:fa:88:95'/>
<mtu size='1500'/>
</interface>
</bond>
</interface>
<!-- incorrectly including guest tap devices, but was an issue
prior and will be fixed in a later series -->
</bridge>
</interface>
Doug Goldstein (6):
interface: Refactor udev bridge to helper func
interface: udev bridge code error handling updates
interface: Refactor interface vlan to helper func
interface: Improve udev backend device type id
interface: add bond support to udev backend
interface: dev type support for bond interfaces

[libvirt] [PATCH] qemu: check backing chains even when cgroup is omitted
by Eric Blake
https://bugzilla.redhat.com/show_bug.cgi?id=896685 points out
a regression caused by commit 38c4a9c - libvirt only labels
the backing chain if the backing chain cache is populated, but
the code to populate the cache was only conditionally performed
if cgroup labeling was necessary.
* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Hoist cache setup...
* src/qemu/qemu_process.c (qemuProcessStart): ...earlier into
caller, where it is now unconditional.
