Hallo List!,
To bring even more confusion to this:
W7 64bit (prof) HVM guest works fine here (i.e. no BSOD like the ones described
here) with:
xen_changeset : Thu Aug 25 12:03:14 2011 +0100 23791:227130622561
Standard qemu, no seabios/upstreamqemu.
OTOH - see the screenshot here:
http://img199.imagevenue.com/img.php?image=84661_win64_strange_cpus_122_233lo.jpg
This "behaviour" is normal here - since Win7_64, in Win7_32 and WinXP_32 this
was no the case iirc.
Windows7_64 seems to have Problems "to start" the CPU (Code: 10) - but with no
visible consquences besides this funny looking devicemanager...
Here's the xen cfg for this guest:
acpi=1
apic=1
boot="c"
builder = 'hvm'
cpus = [ "2", "3", "4", "5", "6", "7" ]
disk = ['tap:qcow2:/home/kaeptnb/.kvm/windows7.qcow2,ioemu:hda,w' ]
gfx_passthru=0
hpet=1
keymap = "de"
memory = '4900'
monitor=1
name = 'win'
on_crash = "preserve"
on_poweroff = "preserve"
on_reboot = "preserve"
on_xend_stop = "shutdown"
pae=1
pci = [ '08:00.0' , '08:00.1' , '00:1a.7' ]
pci_msitranslate=1
pci_power_mgmt = 1
sdl=0
serial = 'pty'
shadow_memory=32
stdvga=1
uuid = "someuuid :)"
vcpus = 6
vif = ['type=ioemu, bridge=br0, mac=anymac:), model=e1000' ]
viridian=1
vnc=1
vncconsole=0
vncpasswd=""
xen_platform_pci=1
Greetings
Tobias
