I downloaded and installed Solaris 10 10/08 as an HVM domU with nv101 dom0. The installation finished with no issues, but every time I try to boot the domain it crashes and the host reboots! Has anyone had any luck running Solaris10 10/08 as a Xen guest? -- This message posted from opensolaris.org
Chris; I have successfully created a Solaris 10 10/08 (Update 6) in an HVM DomU with nv93 dom0. Information about my hardware as given; # virsh dumpxml sol10 sol10 3f25040c-a504-dc5e-882e-43b998f08490 hvm /usr/lib/xen/boot/hvmloader 1597440 1 destroy restart restart /usr/lib/xen/bin/qemu-dm The above works... Command to create the domain as follows... #virt-install -n sol10 -v -r 1560 -c /stage/sol-10-u6-ga1-x86-dvd.iso --os-type=solaris --os-variant=solaris10 -f /dev/zvol/dsk/rpool/sol10 --vnc Warmest Regards Steven Sim Chris wrote: I downloaded and installed Solaris 10 10/08 as an HVM domU with nv101 dom0.

I didn''t get any issue with S10U6 HVM at SNV_101 Dom0. Versus other Xen 3.3 (Linux) Dom0s SNV would load 64-bit Solaris (10/08) HVM by default. Would any other 64-bit HVM DomU load OK at your SNV_101 Dom0 ? ( say RHEL 5.X or Ubuntu Intrepid ) -- This message posted from opensolaris.org

Installing the guest to a ZFS root when using a zvol from the dom0 will still crash the host. Just out of curiosity Steven, did you install your guest using UFS or ZFS? Thanks -- This message posted from opensolaris.org
Chris; UFS for the root disk within the HVM (domU) but ZFS for the root disk for the underlying base system i.e. dom0. The HVM was actually residing on a ZFS allocated device i.e. /dev/zvol/dsk/rpool/sol10''. It seemed to me that ZFS is rather memory hungry and I allocated only 1597440 bytes of memory to the HVM. I then decided not to use ZFS for the HVM root. I''m sure ZFS folks will disagree with my statement on ZFS being a memory hungry er.... feature. :) Warmest Regards Steven Sim Chris wrote: I seem to recall a limitation when using LDOMs where you couldn''t use different ZFS versions for the host and guest.

I''ve the same problem. I reinstalled the guest sol 10 u6 with ufs root but the problem still exist. On host os (b101) I use zfs file system for guests virtual disks. -- This message posted from opensolaris.org
I take back my earlier claim that re-installing S10u6 using UFS fixed the problem. I have a S10u6 guest installed on a Zvol hosted from NV101 and it does boot, but I''ve crashed the host a couple times during the guest boot. I haven''t done a lot of testing, but I seem to have better luck running only a single CPU in the guest. If I have time to test any further I''ll post results. -- This message posted from opensolaris.org

> This sounds very much like a known issue we''re > currently investigating > with SMP solaris guests > > regards > johnThanks for the heads up John. I''ve tried a couple more times and it is clearly a problem with the SMP Solaris HVM guest. Both PV Nevada and HVM Windows guests have no issues with SMP. Bummer that a problem with a guest can blow up the host. -- This message posted from opensolaris.org
