Re: [opensuse-testing] xen problems on 10.3RC1

Peter Sjoberg 09/29/07 12:16 PM >>> I did upgrade a 10.2 system to 10.3RC1 and haven't had much luck with getting the guests running. My problem includes hangs of xend and guests. 1: Use Yast and create a new 10.3RC1 domU. At best I can get it to run

the only way until a later release to get a 10.3 guest is to create the disk image ahead of time dd if=/dev/urandom of=/var/lib/xen/images/VM/disk0 bs=1 count=1 seek=4G or stop the auto reboot at the end of stage one is to stop it and make sure that all of the partitions are unmounted properly. What happens is vm-install tries to mount the image read only after the first stage and since the partition wasn't unmounted properly it thinks something went wrong. As a result, vm-install backs out everything :( ... This has been fixed though, just not in RC1. Stephen the preboot part but (as other reported) then it can't boot for round2 because the kernel can't be found 2: after doing some things "xm" stops working, get a "Error: (9, 'Bad file descriptor')" for "xm list" etc. It seems to happen after I try to start a 10.2 guest but given that I haven't been able to create any 10.3 guest the "create" alone may be the issue.

When I have the last to xenbr added to the vif line it seems like it boots up but then it just hangs and uses 100%cpu. Drop the last two and it boots up ok. I guess this is because the 10.2 xen kernel can't handle the extra vifs so I would like to upgrade the domU to 10.3 but can't find how to do that and my guesses failed. How do I get a domU to "boot" from a .iso image? Given the current state of xen in 10.3 I find it just about useless. Since you can't create new domU it's nothing you can do with it (besides run 10.2 created domU) -- ------------------------------------------------------------------- Techwiz, Peter Sjoberg PGP key (12F506C8) on keyserver & homepage Key fingerprint = 3DC2 CEBA 1590 B41A 3780 955A DB42 02BB 12F5 06C8 mailto:peters AT techwiz.ca http://www.techwiz.ca/~peters -- To unsubscribe, e-mail: opensuse-testing+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-testing+help@opensuse.org -- To unsubscribe, e-mail: opensuse-testing+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-testing+help@opensuse.org
