That implies a bug. Can you attach the full dmesg output, the detailed steps of how you installed it (and the version of Windows). Thanks. Created attachment 548871 [details]

configuration file of vm
I'm not doing anything special. I created a LVM volume and installed windows just that. Windows XP SP2 32bits I'll now install the W7-32bit to see if the same problem occurs. I forgot a few details: Sometimes it happened when I was installing a program under Windows, but not always. Thanks Created attachment 548907 [details]
dmesg results
Hi, This bug occurs whenever I make a massive processing. For example was installing an SDK and the bug occurred several times. This test done using the kernel-3.1.5-2.fc16.x86_64 and the problem is the same as in kernel-3.1.5-6.fc16.x86_64 thank you Volnei, Thanks for uploading all those logs. Looking at the kernel stack it looks as if the kernel detects processes being stuck for a very lengthy time doing something. Most of that something is with a hypercall, meaning that the xen hypervisor is doing something for a very long time - which it should not do. Can you on the xen hypervisor line add 'loglvl=all guest_loglvl=all' and when see those errors again, run 'xm dmesg' and attach the output here? Also run 'xm debug-keys \*' and that should print tons of detailed information. The other thing that I wonder if you could is try installing the PV drivers. There are GPL version of them: http://www.meadowcourt.org/downloads/ [and here is a good link in case you run in trouble:http://www.jolokianet.net/70Knowledge/Virtualization/Open_Source_Windows_Paravirtualization_Drivers_for_Xen] Thanks. Ok. Two questions: 1) Where I put the parameters (loglvl=all guest_loglvl=all')? Already that I use the kernel = "/usr/lib/xen/boot/hvmloader"? 2) In case, I'm using the XP w/SP3. Wich driver I should install? I install gplpv_xp_0.11.0.308.msi is this the right? Thanks Created attachment 549070 [details]

xm-dmesg
Hi, I was compiling two programs simultaneously in VM XP, and the problem has occurred.The VM was using only 1 vcpu. By curiosity I reconfigured the VM to use 2 vcpus and redid the compilations and the problem didn't happen. I already had installed the gplpv_XP_0.11..0.308.msi I hope that this information can help you Thanks Created attachment 550675 [details]
