[libvirt] qemu-kvm blocked for more than 120 seconds when "libvirt-guests" is enabled

[Tomáš Golembiovský]

Hi,

this is just a guess, but from the screenshot I see that NFS is already
down. Are your VMs local or do you use NFS storage or some other network
storage pool? That would be a reason for qemu process to hang.

Best regards,

    Tomas
