[pve-devel] KVM guest hangs with SCSI drive (ZFS)

[Adrian Costin]

Hi guys,

I'm trying to install a KVM guest using a SCSI drive and the installer
always hungs around when it loads the scsi modules. I've tried CentOS,
Debian, Ubuntu with no luck.

I've also tried to install the guest using VirtIO or IDE and switch to
SCSI after the fact with the same result.

I'm running the latest packages with the 2.6.32-29-pve kernel and
pve-qemu-kvm 1.7-8 and using the ZFS Plugin which passes a iscsi url
to the KVM command. I've tried both default and VirtIO SCSI HW.

Running the same guest with VirtIO, SATA or IDE works without any
problems and also running a qcow2 local SCSI drive works.


Best regards,
Adrian Costin
