ciao, I have a problem to run a 64 bit intel guest inside a 64 bit intel host. It doesn' boot.
host: Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz
OS: ubuntu 8.10 64 bit
($ file /bin/ls>/bin/ls: ELF 64-bit LSB xecutable, x86-64,...)
kvm-82
$ modinfo kvm
filename: /lib/modules/2.6.27-9-server/extra/kvm.ko
license: GPL
author: Qumranet
version: kvm-82
srcversion: 26E72577C6F752FF6FCE2AE
depends:
vermagic: 2.6.27-9-server SMP mod_unload modversions
parm: oos_shadow:bool
parm: msi2intx:bool
$ modinfo kvm_intel
filename: /lib/modules/2.6.27-9-server/extra/kvm-intel.ko
license: GPL
author: Qumranet
version: kvm-82
srcversion: 6F53E897CA902DDC25AC326
depends: kvm
vermagic: 2.6.27-9-server SMP mod_unload modversions
parm: bypass_guest_pf:bool
parm: enable_vpid:bool
parm: flexpriority_enabled:bool
parm: enable_ept:bool
parm: emulate_invalid_guest_state:bool
trying to boot the guest:
/usr/local/bin/qemu-system-x86_64 -cpu core2duo
-hda ./ubuntu-server-8.10_64bit.root
-cdrom /home/vm/iso/ubuntu/ubuntu-8.10-server-i386.iso
-k it -usbdevice tablet -boot d
as soon as I run this command, in syslog appear:
cpu0: unhandled wrmsr: 0xc0010117 data 0
(always the same address)
and in the guest window, the latest 3 lines:
Initializing cgroup subsys ns
Initializing cgroup subsys cpuacct
Initializing cgroup subsys memory
(screendump in attachment)
the same with -cpu: coreduo
no problem (but still appear "unhandled wrmsr" error) with
all the other cpu
questions:
1) with -cpu qemu64 I obtain in the guest:
cat /proc/cpuinfo
vendor_id: GenuineIntel
but it doesn't seem a 64 bit cpu (?)
2) can I do some deeper debug to provide more useful info?
(or suggest me a different command-line)
3) what does "logfile" command (should) do?
CTRL-ALT-2
logfile /tmp/logfile
but there is no /tmp/logfile on host
thank you.
