hello all
when trying to create a VM using a RAW image on a zfs filesystem, i get an
"invalid argument" error.
has anyone made this work? is it a known issue and/or is there a workaround?
more detail:
- i can create the VM on a ext4 filesystem
- i can create the VM on a ZFS zvol ("raw" device - too slow, however)
- linux is centos 6 (2.6.32-71.el6.x86_64 )
- zfsonlinux is v0.6.0 (http://zfsonlinux.org)
- qemu-kvm is v0.12.1.2 ; release 2.113.el6_0.8
- copying the VM disk from ext4fs to zfs & then running it results in a similar error
disk creation line was:
# qemu-img create -f raw elveros_001.raw 15G
full error was:
Unable to complete install '<class 'libvirt.libvirtError'> internal error Process exited while reading console log output: char device redirected to /dev/pts/3
qemu: could not open disk image /space/vm_store/elveros_001.raw: Invalid argument

if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)
any suggestions in getting ZFS as the vm_store, working with decent performance ?
