[Xen-devel] Guest Win7 VGA passthru display video cause host Fedora hang issue on XEN4.1

["Cao, Buddy" <buddy.cao@xxxxxxxxx>]

Hi guys, I set up XEN4.1 on fedora 14 64bit, and install guest Win7 which vga passthru display videos by Windows Media Player. I left the video running entire weekend, after I’m back on Monday, the screen freezed and fedora was not accessible via ssh or vnc. I tried again, found this issue is intermittent,  there are 50% odds to reproduce the issue after running 3+ days.

 

Attached is the logs I have when the issue occurs.

 

Hardware: Intel Sandy bridge platform, Intel(R) Core(TM) i7-2655LE CPU @ 2.20GHz, 320G HDD, two 2G Kingstone DDR3 memories

 

xend-config.sxp

(xend-unix-server yes)

(xend-http-server yes)

(xend-relocation-server yes)

(xend-port 8000)

(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$')

(network-script network-bridge)

(vif-script vif-bridge)

(dom0-min-mem 512)

(enable-dom0-ballooning yes)

(total_available_memory 0)

(dom0-cpus 0)

(vnc-listen '0.0.0.0')

(vncpasswd '')

 

 

guest win7 .cfg

import os, re

arch = os.uname()[4]

name = "GuestOS_Backup"

maxmem = 2048

memory = 2048

vcpus = 4

builder = "hvm"

kernel = "/usr/lib/xen/boot/hvmloader"

boot = "c"

pae = 0

acpi = 1

apic = 1

timer_mode =1

shadow_memory = 32

device_model = "/usr/lib/xen/bin/qemu-dm"

vnc = 1

disk = [ "file:/opt/EVM/domain/a.img,hda,w" ]

vif = [ "type=ioemu" ]

audio = 1

 

gfx_passthru=1

pci = ['00:02.0','00:1f.0','00:1a.0','00:1d.0','00:1b.0']
