[libvirt] [PATCH] qemu_migration: Don't error on tunelled migration with --copy-storage
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=979477
Since 1.0.3 we are using the new way to copy non shared storage during
migration (the NBD way). However, whether the new or old way is used is
not controllable by user but unconditionally turned on if both sides of
migration support it. Moreover, the implementation is not complete: the
combination for VIR_MIGRATE_TUNNELLED flag is missing (as we need to
open new port on the destination) in which case we just error out. This
is deadly combination: not letting users choose their destiny and
erroring out. We should not do that but VIR_WARN and turn the NBD off
instead.
---
Probably worth backporting to v1.0.3+ maint branches too.

[libvirt] virsh [attach-detach]-device question
by Scott Sullivan
I have noticed a behavior I am hoping someone can help me understand.
Consider the following scenario:
1.) Start a test dummy qemu-kvm instance with no OS via virsh named "no_os".
2.) Attach a device to it;
[root@host ~]# virsh attach-device no_os /root/hotplug_device_b.xml
Device attached successfully
[root@host ~]#
3.) Now detach the same device;
[root@host ~]# virsh detach-device no_os /root/hotplug_device_b.xml
Device detached successfully
[root@host ~]#
4.) Now re-attach the same device;
[root@host ~]# virsh attach-device no_os /root/hotplug_device_b.xml
error: Failed to attach device from /root/hotplug_device_b.xml
error: internal error unable to execute QEMU command 'device_add':
Duplicate ID 'virtio-disk1' for device
[root@host ~]#
Is this expected behavior? If so, why does my detach-device call in step
3 appear to not free the device, leading to the duplicate ID error in
step 4?
Libvirt XML's used:
/root/hotplug_device_b.xml:
<disk type='block' device='disk'>
<driver name='qemu' cache='none'/>
<source dev="/dev/syseng/hotplug_test_b"/>
<target dev="vdb" bus="virtio"/>
</disk>
I started the "no_os" instance with this:

[libvirt] [PATCHv2 0/7] Q35 support part 2 - RESEND with a few small changes
by Laine Stump
This obsoletes patches 3/7-10/7 of the previous posting of Q35 part
2. The first 3 patches had been ACKed so I pushed those, so patch 1/7
of this series was 3/7 of the v1.
Most of the changes to patches 1-4 are small nits that I neglected to
keep track of (e.g. fixing make check when run as each patch is
applied, and changing the commandline args slightly as I figured out
issues once I could actually start up and run a domain.
The issue with pci.0 vs. pcie.0 has been fixed in this new series. As
indicated in my latest response to the previous series, with the 3 new
additional patches everything seems to work.
A default USB controller is still not added for Q35 machines
domains. domains that are created now will continue to be compatible
once we decide what type of default USB controller to add though (if
we do decide to do that).
At this point I am declaring the Q35 support in libvirt
"usable". Until some tweaks are made to virt-manager, it won't be
possible to create a new q35 domain with virt-manager though.

[libvirt] [PATCH 0/7] Q35 support part 2
by Laine Stump
This series adds everything needed to create and start a Q35 machine
from libvirt, with a couple of small exceptions:
1) Although the implicit pcie-root controller on q35 machinetypes is
referred to as "pcie.0" by qemu, the code as it stands now still puts
"pci.0" on the commandline, which means it's still unusable. I'm
working on a patch to fix that right now.
2) The q35 machinetype doesn't create a default usb controller as the
other machinetypes do. The reason for that is explained in Patch
7/7. I think we probably *should* have a default usb controller added
for q35 (just to make creating a new machine config easier), but it
probably should be a usb2 "trifecta" of controllers, rather than an
old-fashioned usb1 piix3 controller.
With (1) fixed, this should be enough functionality that people can
start testing q35 guests via libvirt.

It sounds like it's a safe bet to assume that -vga will put the device
on slot 2 for pc machinetypes and slot 1 for q35, no matter what other
devices there are, since -vga is always initialized first. Correct? Do
you see any chance that might change in the future? (e.g. due to some
other new device that needs to be initialized even before vga)

Are you saying that it's still required to use -vga instead of -device
qxl-vga for pc machinetype? Or that it was needed at one time, but that
is no longer the case? If the latter, is there a reliable way to make
the decision whether or not we need to use -vga?

What is the replacement ? We need to be able to query whether
each of suspend, hibernate, or suspend-hybrid are supported on
a host, and then report that upto the mgmt app using libvirt.

[libvirt] [PATCH 0/9] qemu: Support qemu-system-arm vexpress-a9
by Cole Robinson
This series adds the bits needed to kick of a qemu-system-arm -machine
vexpress-a9 guest.
Patches 1 and 8 are isolated bug fixes
Patches 2-5 and 7 are mostly about fixing CLI generation. Unfortunately
qemu ARM boards don't quite work like x86 where we can mix and match
devices, so -device is out of the picture, and the boards depend on
old CLI infrastrucure like -net nic and -serial.
Patch 6 adds disk bus=sd, which is often the only way to specify storage
for ARM boards.
Patch 9 adds virtio-mmio address support, which enables virtio
for vexpress-a9.
Cole Robinson (9):
qemu_command: Drop incorrect ATTRIBUTE_UNUSED annotation
domain_conf: Set QEMU ARM default USB model to 'none'
domain_conf: Don't add default memballoon device on ARM
qemu: Fix adding specifying char devs for ARM
qemu: Don't try to allocate PCI addresses for ARM
domain_conf: Add disk bus=sd, wire it up for qemu
qemu: Fix networking for ARM guests
qemu: Only setup vhost if virtType == "kvm"
qemu: Support virtio-mmio transport for virtio on ARM
