[Xen-users] DomU crashes sometimes on startup - PCI-Passthrough
Hi, I''m using currently Xen 3.3.1 with three paravirtualized Guests. I have passed through PCIe-NIC to every Guest. That works basically great, but with two Guests I have sometimes problems at Startup: When I type "xm start Dom1 -c" the xm-command returns sometimes without any output. "xm list" then shows that the Dom1 is not running. When I try "xm start" again it works mostly and the VM is starting up. And when it''s running I don''t have any stability-problems or so. The only warning message I''ll find in xend.log is the following: [2009-12-09 11:14:36 3044] WARNING (pciif:412) pci: 0000:00:09.0: it is on bus 0, but has no PCI Advanced Capabilities for FLR. Will try the Dstate transition method or some vendor specific methods if available. [2009-12-09 11:14:38 3044] WARNING (XendDomainInfo:1645) Domain has crashed: name=Dom1 id=1. I use two onboard PCIe-Ethernet Devices (NVidia MCP55) and one on a separate card (Intel e1000e). The e1000e is assigned to Dom3 (with "pci=[ ''0000:05:00.0'' ]" in VM-Config) and for pci-device 0000:05:00.0 I don''t get such a FLR-Warning. For both NVidia-Devices I get such a warning and sometimes they crash on startup... Any Hints? -- Dieter _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
