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

I think you need to set up a serial console to be able to capture the crash logs on another computer. http://wiki.xen.org/xenwiki/XenSerialConsole http://wiki.xen.org/xenwiki/XenParavirtOps -- Pasi> > 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 > > on_poweroff = "destroy" > > on_reboot = "restart" > > on_crash = "restart" > > 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''] > > > > > > Thanks, > > Wei Cao | ZZH2 2W081 | 8 821 5739 | 021 61165739 | > [1]http://flexservices.intel.com/ > > > > References > > Visible links > 1. http://flexservices.intel.com/> _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
