New: Whole system crashes when sharing network card in virtual PC only on kernel 3.11
https://bugzilla.kernel.org/show_bug.cgi?id=64601
Bug ID: 64601
Summary: Whole system crashes when sharing network card in
virtual PC only on kernel 3.11
Product: Virtualization
Version: unspecified
Kernel Version: 3.11.*
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: kvm
Assignee: [email protected]
Reporter: [email protected]
Regression: NoI have fedora 19 on 2 x86_64 computers and 2 686 computers
i use virtual machines on all of them, it works fine on the 686 computers
but on my 64 bit computers as soon as the kernel upgraded to 3.11 my virtual machines crash the whole system if i use a ethernet card that is shard with a physical card... .the virtual pc works fine if i use the virtual network but if you share the physical device it just freezes the whole system, happens on both of my 64 bit computers, and really is bad.

i should add that when i boot up with the older 3.9 kernel the virtual machine with shared network cards work, and if i boot with any 3.11 kernel it locks up the host when launching virtual pc with shared nework card

i am using the virtual machine manager, i dont know what the libvirt.xml you want is but when i launch it this is the process it runs
/usr/bin/qemu-system-x86_64 -machine accel=kvm -name Windows7 -S -machine pc-i440fx-1.4,accel=kvm,usb=off -m 3000 -smp 2,sockets=2,cores=1,threads=1

my kernel upgraded to 3.11.7-200 and still does the same thing, i just tried again on one of my 64 bit computers i tried kernels 3.9.5-301, 3.9.8-300, 3.9.9-302 and the virtual machine above runs perfectly fine.
i tried on 3.11.1-200, 3.11.3-201, 3.11.6-200, and now 3.11.7-200 and they all freeze the host.... if i remove the hardware, and add it as a virtual network it will work, if i remove the hardware and then boot the virtual pc, and add the hardware while its running, as soon as i add it, the host freezes up have to hard reset.
Thanks.

--- Comment #4 from Luke Hinds <[email protected]> --- You can source the libvirt xml with virsh
$ virsh connect qemu:///system Connecting to uri: qemu:///system
$ virsh dumpxml foo > /tmp/foo.xml
