Reproducible: Always Steps to Reproduce: 1. Install 64 bit opensuse 11.2 2. Create HVM guest with 32 bit opensuse 11.2 3. start the guest using xm start and open a console to it 4. Compile a kernel in dom0 with 'make -j 8' to generate some load. Actual Results: DomU freezes as soon as the kernel compilation is under way. Dom0 itself remains responsive. Messages about soft lockups and CPU#<n> stuck start appearing. Expected Results: DomU should have been responsive, albeit a bit slower, but not completely unresponsive.. Using stock kernel 2.6.31.12-0.1-xen (dom0) and 2.6.31.12-0.1-desktop (domU). Hardware Core i7 720QM, 8gb memory, 500GB hard disk. Sony Vaio F11 laptop. Problem appears with both credit scheduler and sedf scheduler. Xen boot option noapic does not help. Manipulating caps and weights with the credit scheduler also does not have any effect. This feature in effect renders xen useless. I am evaluating Xen on my laptop for more serious uses on a server and the current behavior of xen is blocking for that. Will have to consider other virtualization options if this problem is not solved. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

No apparent loss of reponsiveness in the domUs when putting high CPU load on dom0. Also, in general, the domUs feel faster. Also tried to install Xen 3.4.2 with the 2.6.18 kernel (from Xen) but could not boot the system in that case because of an incompatibility of LVM on opensuse11.2 with that old kernel version. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hmm, okay - so far, partly from your post on xen-devel, I was under the impression that Dom0 is also misbehaving for you.

Because of the issues with the stock xen kernel of opensuse 11.2 I was trying the xen/master kernel. However, that one gave a problem booting dom0. I am able to boot that kernel now but when I use the xen 3.4.2 hyper visor that I downloaded and compiled (with kernel 2.6.18) I get another problem in starting xend (xend keeps on recursively starting xend), so I can only use the xen-3.4.1 version from SuSE with the xen/master kernel. The problem is then, however, still there. It would also help if I could compile a new xen version and try that, but I don't know how much the xen hypervisor is tied to the kernel version. I would expect that there would only be a dependency of the kernel running as dom0 on the hypervisor interface but that the hypervisor would be independent of the kernel. In summary, I can bootup with xen-3.4.2 but in that case the /etc/init.d/xend script fails horribly. Would it be safe to use the xend binary from the 3.4.2 distribution together with the /etc/init.d/xend script from SuSE (xen-tools-3.4.1_19718_04-2.1.x86_64)? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I would expect that there would only be a dependency of the kernel running as dom0 on the hypervisor interface but that the hypervisor would be independent of the kernel.

Generally, replacing the hypervisor with a newer one should cause no problems (apart from the system becoming completely unsupportable if you do this for other than problem analysis) with either Dom0 or DomU kernels - anything else would be a bug. Xend, however, has to match the underlying hypervisor, so if you update that one you'll also have to make sure you use the corresponding newer tools. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hence I'm lowering the priority. The situation would be different if the same issue happened with multiple guests starving each other. Nevertheless I ran comparable workloads (kernel compile in Dom0 and DomU each fully saturating the CPUs, i.e. 200% overall load) without seeing similar effects. Hence there must be more to this than the bare workload.

http://bugzilla.novell.com/show_bug.cgi?id=583867 http://bugzilla.novell.com/show_bug.cgi?id=583867#c17 --- Comment #17 from Erik Brakkee 2010-03-04 17:43:25 UTC --- I agree with the remark that putting load on dom0 is a bad idea when it comes to a normal server setup. In such a case, indeed, the task of the dom0 is indeed to service guests. However, another use case that is getting more and more popular these days is that of a desktop user running a virtual appliance. Apart from whether it is a bad idea to put such a load on dom0, it does appear that doing that leads to starvation of the domU. This would mean that also on a correctly setup server, this can result in a bad performance of domUs in cases where there is some load on dom0. In my case, I am not putting load on domU, but when I do (e.g. kernel compilation using make -j 8 on domU), and then start a similar kernel compilation on dom0 I am seeing the same phenomenon, where domU is starved,. Because of this I think it is still a serious problem and it will probably result in unstable server setups where domUs will sometimes be unresponsive or extremely slow. Therefore, I think it is premature to lower the priority of this problem. I am running this on specific hardware (Core i7-720QM) so perhaps the problems is related to that. Have you also tested this on similar hardware? Also, I had a much better experience running the xen live cd (see earlier comment), so it is definitely a new problem. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

A tentative fix for this was just committed, will be available in a future kernel maintenance update - please re-test against that.

I have tried in the past to build my own xen kernel but as I understand it Xen is very closely integrated with the kernel. If you can provide me with a reference to a kernel version with Xen included then I could try (and some instructions on how to build). However, my best hope is in trying it out in a new opensuse 11.3 version. Can I expect the patch to be in there? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I am running this on a Sony Vaio F11 (corei7 720QM). In the old situation, the compilation output of the guest would stop immediately as soon as any load is put on the server.
