[libvirt] virtual machine won't autostart when using LVM with cache
Hello guys, OS Fedora 23 with latest updates Recently I have switched to use LVM cache feature on logical volume /dev/hdd/windata1 to improve it performace using 32GB partition from SSD disk. However, when my computer will start, my virtual machine won't autostart Mar 21 10:48:57 brutus-coreos libvirtd[956]: Cannot access storage file '/dev/hdd/windata1' (as uid:107, gid:107): No such file or directory Mar 21 10:48:57 brutus-coreos libvirtd[956]: Failed to autostart VM 'winos1': Cannot access storage file '/dev/hdd/windata1' (as uid:107, gid:107): No such file or directory Mar 21 10:48:57 brutus-coreos libvirtd[956]: Cannot access storage file '/dev/hdd/windata1' (as uid:107, gid:107): No such file or directory It seems that when using LVM cache, one have to wait till it will inicialize? When I will manually start virtual machine afterwards, everything works OK : [root@brutus-coreos ~]# virsh start winos1 Domain winos1 started I have tried to remove LVM cache from /dev/hdd/windata1 and afterward autostart works! So it must be LVM cache related. Can you please help me to solve this ?

Maybe override the system libvirtd unit file to wait for LVM. There's some details here, but I didn't test it: https://ask.fedoraproject.org/en/question/10419/how-to-start-a-systemd-unit-... - Cole
