Bug#657617: xen-qemu-dm-4.0: Windows 2008 R2 VM reboot with SMP and high I/O-Load (bugcheck 101)

Package: xen-qemu-dm-4.0
Version: 4.0.1-2
Severity: normal


"Windows 2008 R2" virtual machine reboots after ~ 10 minutes of high I/O load in case of using more than one vcpu (see xen configuration below). The qemu-dm-Logile says "XenPCI Bug check 0x00000101 (0x0000000000000030, 0x0000000000000000, 0xFFFFF880009B8180, 0x0000000000000001)" (see logfile below). Microsoft says, bug check 0x101 is caused by "The specified processor is not processing interrupts. Typically, this occurs when the processor is nonresponsive or is deadlocked. " (see here: http://msdn.microsoft.com/en-us/lib...85%29.aspx)

To reproduce this error, i just copied some big files (~ 5 GiB each file) within the virtual machine from one folder on drive C: to another folder concurrently. After approx. 10 minutes, the crashs and reboots automatically. I disable "shadow_memory", "acpi" and "apic" but this doesn't work either.

But when I remove the cpus and vcpus - parameter from the xen config files, the default value of only 1 cpu to be used by the virtual machine, everything works fine. The virtual machine seems to be stable although copying files as done before some hours long.

Hi Markus,

What driver did you use? Did you install some Windows PV drivers?

I tried both, with and without PV driver, but it doesn't make any
difference. I used driver version 0.10.0.130, haven't tried the signed driver, yet.
