hello, in my windows vm i installed qemu-guest-agent and rebootet the vm. In the settings for the vm i set via virt-manager a new channel "unix socket" "org.qemu.guest_agent.0" "virtio". when i try to do a snapshot via shell i get: virsh snapshot-create-as --domain win7new win7new-snap1 --disk-only --atomic --quiesce error: Guest agent is not responding:

Hello, thanks for the information. Please let me ask: If understand correctly this issue occoured and reported in 3.9? And the fix is for 3.11 or 4.0?

The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. However, that approach produces an invalid page address when we read/write to vmalloc buffers, such as those used for Linux kernle modules. This causes QEMU to die printing:

Hi all, I'm trying to share a folder between a host and a guest using VirtFS. The source is NAS mounted on the host and QEMU runs as unprivileged user. The only way for me to use the folder inside the guest is to set the access mode to 'squash' but all file operations are performed by the user running QEMU. If I ran QEMU as root, the passthrough mode works as expected. Is there

Hi Daniel, here are any informations. A little bit strange, coredumpctl showthe libvirtd. coredumpctl dump libvirt and info libvirt  no information.

[CC to qemu-devel since I'm obviously doing something wrong here, I'm just not sure what.] I was getting ready to add multiple threads to ‘qemu-img convert’ (the longest part of v2v conversions) when I noticed that it had them already! (To be fair this was only added in February this year so no wonder we didn't notice.) To enable parallel convert we would need to use the ‘qemu-img

Hello, I've been trying to boot a VM with the rootfs being a 9P share from the host. The VM OS is centos 7. The OS boots but no services can work and it appears that the authentication system is broken. Now the funny thing is that booting the same OS on the same 9P share manually with Qemu works as expected with a fully functionnal OS... So I'm wondering what could libvirt do that render

It's not limited and can be modified inside the xml, the only limitation is that the value has to be a power of 2 and for QXL the value must be at least 1024. There is an exception, qemu can and in some cases updates
