[Bug 1847440] Re: ppc64le: KVM guest fails to boot with an error `virtio_scsi: probe of virtio1 failed with error -22` on master

[David Gibson <1847440@bugs.launchpad.net>]

Oh... are you using the SLOF (guest firmware) image included in the qemu
tree, or is it coming from a separate package?


If it's from a separate package, that could be the problem - it needs to be updated before that qemu patch is safe.
