Network bridges in F12 beta
by Andrés García 09 Nov '09

09 Nov '09

Hi, I think I read somewhere that with Fedora 12 there was going to be a way to configure virtual network bridges automagically. I have looked for it in virt-manager and network manager but it doesn't seem to be there, so I guess my memory is fooling me, right? So, if I have to do it manually, do the instructions at: http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared… still apply? Thanks, Andrés

Connect from remote host
by Andrés García 05 Nov '09

05 Nov '09

Hi, I configured a Fedora 12 beta system to accept connections from other system as explained here: http://virt-manager.et.redhat.com/page/RemoteDigest To test it I connected using virt-manager in that system to itself and it worked, but when I tried from a F11 virt-manager in another system it fails, I also tried connecting with virsh: # virsh virsh # connect qemu+tcp://192.168.0.43 It tells me there is no route to host despite being able to ping 192.168.0.43. Any ideas what could be wrong? F12 has a firewall I am not aware of? Thanks, Andres Garcia

Do you have a reference to how the bridges would be crafted in libvirt XML?

Mount guest filesystems in the host
by Richard W.M. Jones 03 Nov '09

03 Nov '09

Little bit quiet on this list at the moment, so here's some news ... We just built a package called 'libguestfs-mount' in Rawhide which lets you mount virtual machines' filesystems on the host, using FUSE. http://koji.fedoraproject.org/koji/buildinfo?buildID=139621 Use it like this (as non-root): mkdir /tmp/mnt guestmount -a disk.img -m /dev/VG/Root --ro /tmp/mnt where you can replace 'disk.img' with any guest's disk image, and /dev/VG/Root with the root device in that guest. Or to get virt-inspector to do the hard work of looking in the guest and arranging the disks for you: guestmount $(virt-inspector --ro-fish MyGuest) /tmp/mnt where MyGuest is the name of the guest (as known by libvirt). And then you can just look into /tmp/mnt and browse the guest's disk using whatever text or graphical tools you want. To unmount do: fusermount -u /tmp/mnt Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-p2v converts physical machines to virtual machines. Boot with a live CD or over the network (PXE) and turn machines into Xen guests. http://et.redhat.com/~rjones/virt-p2v
