by Kevin Wilson 26 Nov '12

26 Nov '12

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=Virtu… 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 14 Nov '12

14 Nov '12

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?

virt-v2v hang
by Ian Pilcher 13 Nov '12

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?

Cannot set MTU on bridge
by Ian Pilcher 02 Nov '12

02 Nov '12

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! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com Sometimes there's nothing left to do but crash and burn...or die trying. ========================================================================

Did you try setting the mtu on the physical interface? -------- Original Message -------- From: Ian Pilcher <arequipeno(a)gmail.com> Sent: Thu, 01/11/2012 06:22 PM To: virt(a)lists.fedoraproject.org CC: Subject: [fedora-virt] Cannot set MTU on bridge I am trying to create a bridge for use as an iSCSI storage network.
