Hi all, I''ve just upgraded my OpenSolaris 2008.05 workstation to snv_90 after unsucessfully trying to get virt-install.sh to run on snv_86 and now have (I think) a more serious problem. In the xend-debug.log file I keep getting the following error repeated many times : Failed allocation for dom 8: 1 extents of order 9 ERROR Internal error: Cannot allocate more 2M pages for HVM guest. (16 = Device busy) Does anyone have an idea why?? I am attemping to create a Windows XP HVM using a ZFS volume as the target disk. Regards, Nick -base-3.2 # virt-install --name winxp --ram 1024 --cdrom /var/tmp/winxppro32.iso \ --file /dev/zvol/dsk/rpool/winxp --vnc --hvm --os-type windows --os-variant win2k \ --bridge e1000g0 --debug This message posted from opensolaris.org
How much memory does your machine have? Have you limited dom0_mem or the ZFS arc cache? See previous threads on these topics. In order to use ZFS effectively in dom0, you''ll need to do one or the other, at least.

The machine is a Sun Ultra 24 with 4GB RAM. I have limited the ZFS arc cache to 1GB. Does anyone have any idea what device might be busy? Is the the message about failed allocation of memory a red herring?> How much memory does your machine have? Have you limited dom0_mem or the > ZFS arc cache? See previous threads on these topics.

I have now reinstalled 2008.05 (b86) and upgraded the system to b91 and unfortunately the same issue occurs with the failed memory allocation. Any help would be most appreciated as I need to run the guest OS! Regards, Nick This message posted from opensolaris.org
