#186 OpenSolaris 64bit panic with kvm-54
Wouldn't mark it as a regression per-se as vanilla kvm-53 wouldn't work (because of the need for IDE patches to get it to run/install), but vanilla kvm-54 or kvm-54 + the same patches added to kvm-53 and including pre-kvm-55 patches like 71be592a14aa8d127315b2c47bf83cc0d810a341 wouldn't work.
The panic is observed in kvm-54 (--no-kvm runs ok, and --no-kvm-irqchip doesn't help) while running nexenta OpenSolaris alpha 7 or beta 1 (other OpenSolaris distributions most likely affected as well) and with the following trace :
panic[cpu0]/thread=fffffffec2de2260: BAD TRAP: type=e (#pf Page fault) rp=ffffff0001735f30 addr=0 occurred in module "unix" due to a NULL pointer dereference

kvm-53 also crashes randomly so it might not be a regression anyway, but though it might be interesting to mention that kvm-54 + previously detailed patches and also including fixes for is_long_mode as reported here :
http://www.mail-archive.com/kvm-devel%40lists.sourceforge.net/msg08947.html
are able to run most versions of Solaris 10 64bit x86
Hi,
I notice this one has been open for a long time. If you are still interested in this, could you please try it against a recent KVM. If that works fine, lets close this bug.
Thanks,
Jes
saw this with OpenSolaris 2009.6 (booting from iso, freely available) under a fully updated Fedora 13 (qemu-kvm-0.12.3-8.fc13.x86_64). using a 32bit-CPU for the guest works fine.
Interesting, can you give me a pointer to where I can download that ISO image from?
Thanks,
Jes
simply from the OpenSolaris-website:

Release 2009.06 for x86, installing it with x86_64-processor in KVM
Hi,
I pulled down the iso image you mentioned, and it seems to boot fine for me here. I was able to run the install to a local disk image and boot it again afterwards. This is using a 64 bit guest CPU on a Fedora 12 system.
What flags are you using to launch it when you see the crash? Are you running on an Intel or an AMD system and did you specify SMP by any chance?
Cheers,
Jes
Hi,
I didn't see any replies to my question as of June 21, are you still seeing this? I wasn't able
to reproduce this in my testing.
Regards,
Jes
Works for me per previous comments. If you see this again, please open a new bug in Launchpad.
Thanks,
Jes
