I'm trying to create an x86 64 bit guest machine on an old Debian Lenny x86 64 bit hypervisor using HVM. The physical CPU is a first generation Intel i7 with VT-x support. Xen recognizes the VT-x support with the line (XEN) HVM: VMX enabled when running xm dmesg.
The Xen version according to xm info is 3.2.
I tried with newest installer ISO images of Debian Squeeze (6.0) and Ubuntu Oneiric Ocelot (11.10). The x86 64 bit version freezes the guest system shortly after starting, if I mount the x86 32 bit installer image, everything runs fine.
How can I fix this?
IRC user krt in ##xen on irc.freenode.net recommended setting acpi = 0 in the guest configuration file. This did not solve this problem.
Here is the guest configuration file I'm currently using:
arch = 'amd64'
device_model = '/usr/lib/xen-default/bin/qemu-dm'
#
# Kernel + memory size
#
kernel = '/usr/lib/xen-default/boot/hvmloader'
builder = 'hvm'
acpi = 0
#xen_platform_pci = 0
memory = 1024
shadow_memory = 8
#
# Disk device(s).
#
#root = '/dev/sda2 ro'
disk = [
'file:/var/lib/libvirt/images/ubuntu-11.10-desktop-amd64.iso,xvdc:cdrom,r',
'phy:/dev/system/fraumann-root,xvda,w',
]
# boot on floppy (a), hard disk (c) or CD-ROM (d)
# default: hard disk, cd-rom, floppy
boot = 'dc'
#
# Hostname
#
name = 'fraumann'
#
# Networking
#
vif = [ 'ip=1.2.3.4,mac=00:16:3E:9F:3C:31' ] # IP changed for the public
sdl = 0
vnc = 1
vnclisten = 'localhost'
vncconsole = 1
stdvga = 0
serial = 'pty'
usbdevice = 'tablet'
#
# Behaviour

on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
vcpus = 4
extra = 'xencons=tty1'
