installation of win7 with virt-manager fails with "Could not access KVM kernel module"

[Kevin Wilson]

Hi,
I have Fedora 17 and I tries to install from scratch win7 with
virt-Manager and kvm.

What I tried is this;
Followed the instructions here:
https://fedoraproject.org/wiki/Getting_started_with_virtualization?rd=Virtua...

Opened virt-manager as root.
select
   local install media (ISO image or CDROM).

Select:
   Use CDROM or DVD
Select OS type : windows.
Select version: Microsoft windows 7.

accept defaults for Memory (RAM) and CPU.

Select : create a disk image of 25 GB.

Then finish.

I get this error:
Unable to complete install: 'internal error process exited while
connecting to monitor: char device redirected to /dev/pts/6
Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied
No accelerator found!

/dev/kvm  permissions are:
ls -al /dev/kvm
gives:
crw-rw-rw-+ 1 root kvm 10, 232 Nov 23 18:57 /dev/kvm

Any idea what can it be ?

rgs,
Kevin

Hi,
I must add: virt-type (in advance options) is kvm.

I wonder if your hardware supports hardware virt acceleration?

Hi,
Yes it does: we have here vmx, vnmi, tpr_shadow:

cat /proc/cpuinfo | g flags

flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx
lm constant_tsc arch_perfmon pebs bts rep_good nopl aperfmperf pni
dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm xsave lahf_lm
dtherm tpr_shadow vnmi flexpriority

rgs,
Kevin
