Re: [OpenNode-users] Networking issues with KVM machines made with virt-manager

[<ope...@li...>]

As there are 2 different hypervizors on OpenNode - then just to be sure execute:

virsh --connect qemu:///session start kvmdemo1

You can now use also virt-manager - as bridge conf is stored into domain xml file already.

I did a yum upgrade and then I installed a few packages that make me happy like mc, screen, xorg-x11-xinit (so GUI X apps can easy be run over ssh tunnel), etc.  I did not mess with the network configuration.

If it doesn't involve adding too many additional packages, I'd say it would be a worthwhile addition to the functionality.
