I have a similar or the same problem with my Windows Server 2008 R2
virtual machines.  The virtual machine stops with a Blue Screen error
101, clock interrupt was not received on a secondary processor.  The
error only occurs when the VM has 2 cpus.  The error seems to occur when
the VM is some load, over time (hours), or when I RDP to the VM after a
few hours of it running.

The same VM ran perfect under Ubuntu 12.04.

Host Server
ubuntu 14.04 LTS updated from 12.04 LTS
kernel: 3.13.0-30

Virtual Machine
Windows Server 2008 R2
2 cpus (when the error occurs)

Attached is the VM xml configuration file.

I did try adding the  hyperv code and it seemed to help at first, but
then errored in hours.

I did boot to kernel 3.13.0-24 and the same error occurred within an
hour under some load.

Do people expect this problem to be resolved soon?

Thank you for the help.

Bug description:
  
  I noticed on 2 different systems that after upgrade from precise to latest trusty VMs are crashing:

  - in case of Windows VMs I'm getting BSOD with error message: "A clock interrupt was not received on a secondary processor within the allocated time interval."
  - On linux VMs I'm noticing "hrtimer: interrupt took 2992229 ns" messages 
  - On some proprietary virtual appliances I'm noticing crashes an due to missing timer interrupts

  QEMU version is:
  QEMU emulator version 1.7.91 (Debian 2.0.0~rc1+dfsg-0ubuntu3)
