Hi, I am getting a vm stuck problem when booting a windows 7 guest on xen-4.6(latest version). My hvm guest: Windows 7 64bit (installed pvdriver inside, pvdriver is downloaded from 'http://wiki.univention.de/index.php?title=Installing-signed-GPLPV-drivers') My server's CPU model name : Intel(R) Xeon(R) CPU E5-2643 v2 @ 3.50GHz
This happens rarely, maybe only once in hundreds times of rebooting, and when this appens, it stucks on the Windows Logo screen. In order to know where it stopped, I turned on the Boot message and OS Boot Information in OS. It showed something like bellow: " Micfosoft (R) Windows (R) Version 6.1 (Build 7600) 4 System Processors [4088 MB Memory] MultiProcessor Kernel Boot Logging Enabled " then it stucks forever. Then I turned off apicv with option 'apicv=0' and did the rebooting test again, the stuck problem didn't show up for at least 9000 times of rebooting. So I think it is related with apicv, maybe interrupts loss occasionally when vm is booting when apicv is enabled. Has anyone come across this problem before? Or what can I do to solve this? Thank you.
