I'm still interested in knowing what vbox:///system is, but I figured out that I have manually specify -with-xen when building to get Xen support. If after I get the Xen development package and rebuild it still doesn't work, I'll drop a line here. - JT From: Todd, John A Sent: Tuesday, June 08, 2010 1:39 PM To: 'libvirt-users(a)redhat.com' Subject: upgrading from 0.7.2 to 0.8.1 Hi, I had 0.7.2 running as an out-of-the-box version of libvirtd I ran xend and it could connect to xen:/// (with virsh) I'm trying to build a eucalyptus cloud and its not working, saying 'cannot connect to xen:///' and I don't know why. So I figure I'd get the source and try and figure it out....and upgrade while I was at it. I got 0.8.1 from source, built it and installed it. First of all, it installed everything using /usr/local as its root, is this configurable? I mean doing that it left my 0.7.2 still there and I had to do some magic to replace it with the new stuff. Now it connects to vbox:///system fine, but can't see xen:/// What's vbox:///system anyway? Could it be my xend is talking to old binaries? (though I don't know what they would be exactly) Is there some configuration (beyond the certificate stuff which I did to get libvirt actually up and running) with 0.8.1 (or in general as configuration for 0.7.2 was done behind the scene as part of OS install) That I need to do so it can connect to xen:/// again? I'm not subscribed to the list, please email responses directly to me at todjo06(a)ca.com Thanks. - Q
