installation of win7 with virt-manager fails with "Could not access KVM kernel module"
by 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=Vir...
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

Anyone using virt-preview?
by Ian Pilcher
After I sent my note about ifcfg files for fake bridges last night, I
remembered the existence of the virt-preview repo, which would allow
me to run libvirt 1.0.0 on F17.
Before taking the plunge, does anyone know of any major gotchas with
the virt-preview bits right now?
Thanks!

virt-v2v hang
by Ian Pilcher
I am trying to use virt-v2v to convert a Fedora 17 KVM guest to a RHEV
guest. After creating a libvirt storage pool from my existing VG
(uuhg!), I run the following command:
sudo virt-v2v -o rhev -os 192.168.2.254:/srv/nfs --vmtype server -n
rhevm rhev-ipa
Everything appeared to be working until the process (apparently) hung
at 74%. ps shows that it is in a D+ state:
2991 pts/1 D+ 0:10 /usr/bin/perl /bin/virt-v2v -o rhev -os
192.168.2.254:/srv/nfs --vmtype server -n rhevm rhev-ipa
Any ideas? Thanks!

Cannot set MTU on bridge
by Ian Pilcher
I am trying to create a bridge for use as an iSCSI storage network. The
iSCSI target will run on the host (Fedora 17) and the initiators will
all run on KVM VMs. Thus, no physical interface will be added to the
bridge.
For optimum performance, I want to use jumbo frames on the storage
network, so I've created ifcfg-stor0 as follows:
IPADDR=192.168.0.254
NETMASK=255.255.255.0
DEVICE=stor0
ONBOOT=yes
TYPE=Bridge
IPV6INIT=no
DELAY=0
STP=off
NM_CONTROLLED=no
MTU=9000
When starting the interface with ifup, I get "RTNETLINK answers:
Invalid argument", and the MTU is set to 1500.
Trying to set the MTU with ifconfig gives me "SIOCSIFMTU: Invalid
argument".
The workaround I've found so far is to attach a dummy device with the
desired MTU to the bridge:
DEVICE=dummy0
ONBOOT=yes
MTU=9000
IPV6INIT=no
BRIDGE=stor0
NM_CONTROLLED=no
This works, and it's even possible to remove the dummy device after the
MTU is set.
The questions is how can I do this without this awful hack?
TIA!

Re: [fedora-virt] Cannot set MTU on bridge
by Andrew Cathrow
Did you try setting the mtu on the physical interface?
