[Xen-users] Xen dom0 on debian, what is the most recent but stable solution?
I spent many days in the last month to try to have an updated system but stable on debian but I always had problems... Some of you are using latest kernel and xen on debian systems without problems? If yes can you tell me which version of Debian (Lenny and Squeeze), which kernel version (which package or which configuration if compiled manually) and what version of xen use? I have mainly try pv_ops kernel (mainly 2.6.32), mainly xen 3.4 and 4.0 from hg testing and always on lenny 64 bit -- View this message in context: http://old.nabble.com/Xen-dom0-on-debian%2C-what-is-the-most-recent-but-stable-solution--tp28656145p28656145.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It''s recommended to use Xen 4.0.0 + 2.6.32 pvops dom0, since that''s the supported and recommended configuration. -- Pasi> -M > > -------------------------------------------------------------------------- > > 30 days of prizes: Hotmail makes your day easier!

Re: [Xen-users] Xen dom0 on debian, what is the most recent but stable solution?
Kernel seems to ALMOST work for me, but VIF interfaces seem positively bugged beyond functional use. See http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1612 for exact issue I am currently trying to work through. The 2.6.26 as dom0 kernel and any kernel up to 2.6.32-3 as domU I can verify works in most environments. Some newer hardware (SAS6 MegaRAID card for instance) shipping with new Dells fail to boot the 2.26 dom0 kernel and 2.18 lacks driver support for it. Just some random usability feedback from my own testing and usage, I can''t verify absolute stability or promise that my issues aren''t simply configuration-based, but that''s my experience.

Re: [Xen-users] Xen dom0 on debian, what is the most recent but stable solution?
Thanks for the good reply, yesterday on dell t610 i try xen 4.0.1-rc1 with kernel 2.6.32.13 pv_ops last build (last commit f6fe6583b77a49b569eef1b66c3d761eec2e561b) with this config: http://old.nabble.com/file/p28668520/config-2.6.32.13 config-2.6.32.13 Boot very long and system useless Today i have move the same disk to other system not dell, the only problems see with not dom0_mem=...M and balloning of dom0 is low performance if after start of some domU dom0 ram go to 1.4gb approximately and freeze of dom0 (calltrace of out of memory, i can''t log to this system without SOL) when go to 900mb approximately with open of another domU But now with dom0_mem=2048M and dom0 balloning set to no is all ok and good performance Can you recommend me good config for do this system working also on dell server?

Hi,my post will not directly answer your problem. Try to use virsh-manager. It is a nice GUI with which you will be able to do Virtualization even on a server which does not have a GUI running on it. If you consider using it post here I will reply. Which Distribution you are using.

[1]Enter now >>> >>> References >>> >>> Visible links >>> 1. http://go.microsoft.com/?linkid=9729704Figure I''d chime in: I''m up against the same bug. Xen 4.0.0 and pvops dom0 2.6.32-13 (amd64) from Jeremy''s git tree on a x200 Lenovo running a mixed squeeze/sid. I''m getting the same NULL ref in netback_uevent (bug 1612). Funny thing is if the network is hosted from dom0 vif still comes up and works but when the NIC is bound to a driver domain the error causes a command like: ''xm netowrk-attach domU backend=driver_domU'' to fail complaining the hotplug scripts failed to run. The kernel OOPS is then visible in the driver domain. The result is the same for the pvops 2.6.31.13 kernel and the linux-image-2.6.32-5-xen-amd64 kernel packaged in debian sid. If anyone comes up with a work around for this or a relatively recent kernel that works I''d be interested. I wasn''t able to get the 2.6.26 kernel from Lenny to boot Squeeze, any advice there would be great to hold me over till 1612 gets squashed.
