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?
