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

[Alexandre DERUMIER]

maybe can you try with qemu 2.0 ?

(I can built it for you if you want).

Also, I known that booting is not available for all controllers types.


booting from old lsi is a pain, and don't known well since some years known. (depend on multiple parameters)
But the lsi seabios implementation is more a trick
lsi53c810 is a variant, same crap, only for nt4 compatibility.

 

pvscsi boot has been added in this commit:
http://git.qemu.org/?p=qemu.git;a=commit;h=11938d7863203d5ca523865761cac6130783c858

so qemu 2.0 I think.




But I think you shoulg go to virtio-scsi for best performance anyway.

I can confirm that using the 2 packages (libiscsi and qemu-kvm) solves 
the guest kernel hanging when loading modules problem. 

The SeaBIOS problem that doesn't recognize the disks with the 
following drivers still remains: 

scsihw: lsi 
scsihw: lsi53c810 
scsihw: pvscsi 

using scsihw: virtio-scsi-pci or megasas SeaBIOS detects the drive and 
can start grub from it. 

Maybe we need an updated SeaBIOS as well?
