virsh hangs when backup jobs run on the kvm host
Hi,
Has anyone met the same problem that virsh hangs when there are some backup jobs running on the kvm host? I use dirty bitmap supported by qemu to do backups every 6 minitues. About a few hours later, I ran 'virsh list', It hung. Then I stopped the backup jobs ?nothing was getting better. I had checked the libvirt logs ?but found nothing useful .
Maybe the high I/O caused the

Create VM w/ cache=none on tmpfs
Hi,
I've seen that in the past, libvirt couldn't start VMs when the disk
image was stored on a file system that doesn't support direct I/O
having the 'cache=none' configuration [0].
On the KubeVirt project, we have some storage tests on a particular
provider which does just that - try to create / start a VM whose disk
is on tmpfs and whose definition features

Change in treatment of qcow2 with chained backing files in v5.10.0?
Hello list,
upon upgrading from libvirt v5.9.0 -> v5.10.0, libvirt started calling
qemu differently causing the VM operating system to not be found. I'm
wondering whether I'm chasing a bug, or have to otherwise fix my domain
config (created by virt-manager).
To start with, I have a Windows 7 domain based on the following images:

Ouch. qemu-monitor-command is explicitly unsupported, precisely because
it goes behind libvirt's back and is likely to get libvirt confused.

My Windows7 VM stopped at loading screen.
Hello.
I've been tesing VGA passthrough using libvirt.
However, My *Windows7*(64bit) Virtual Machine stopped at loading screen as
soon as I installed graphic driver(*AMD Radeon HD 7750*) and then restarted
the VM.
How Can I use VGA passthrough technology in my *Windows7* VM?
I attached my testing information(HW, system environment and settings, qemu
log and so on..)
Best Regards.

virtlock - a VM goes read-only
Dear colleagues,
I am facing a problem that has been troubling me for last week and a half.
Please if you are able to help or offer some guidance.
I have a non-prod POC environment with 2 CentOS7 fully updated hypervisors
and an NFS filer that serves as a VM image storage. The overall environment
works exceptionally well. However, starting a few weeks ago I have been
trying to implement virtlock

When I live migrate a vm using
