Xen users - Aug 2013 - Solaris PV domU?

Hi,

Anyone had any luck running solaris pv domU recently (Solaris 11.1)? Is
this even supported?

Dom0 is running xen 4.3.0 on ubuntu 12.10.

Failure dump:

root@dom0:/solaris11# xl create -c sol.pvm
Parsing config from sol.pvm
Daemon running with PID 15960
do_bys_alloc_contig: ''align'' 0x40816f40 is less than
MMU_PAGESIZE 0x40816f80
Press any key to reboot.
Resetting...

DomU config file:

memory="4096"
disk=[''/solaris11/sol-11_1-text-x86.iso,,xvdc,cdrom'',''/solaris11/sol.img,raw,xvda,w'']
name="solaris11"
vcpus=2
localtime=1
extra="/platform/i86xpv/kernel/amd64/unix -B -v
console=ttya,livemode=text"
kernel="/solaris11/boot/unix"
ramdisk="/solaris11/boot/boot_archive"

xl dmesg log after the jump.

Thanks,
Mark

Hi,

I''ve read on the wiki that graphics passthrough from multiple VMs to
one head is a non-starter
(http://wiki.xen.org/wiki/Xen_VGA_Passthrough#Can_I_share_the_graphics_card_between_multiple_VMs_with_Xen_VGA_passthru.3F).

However, in the case of passing the video card via PCI-Passthrough to the Dom U
(without setting gfx_passthru to true), should the same non-starter behavior be
expected?  Or, should I be able to implement pci-detach said video card from one
DomU and reattach to another?

Please let me know if I can provide any further clarification.
