Hello, I have been struggling through the task of moving our infrastructure over to Xen VMs. We were initially using Ubuntu packages for both dom0 and our domUs, but experienced extreme instability so we moved to CentOS, which has been much more reliable for dom0. Since we already had a bunch of Ubuntu VMs, we left them using the Ubuntu 2.4.24-19-xen kernel, but this has turned out to be

Hi, my system got updated to libvirt 6.0.0 (from 5.6.0) this morning, and now I'm having problems starting VMs that make use of openvswitch portgroups.

Hi, I'm using qemu+ssh://username at hostname/system as the remote URI. Libvirt seems to be communicating fine until some 2 minutes (we poll every 5 seconds) and then it throws up RPC error and many counters are wrong. But if I collect on localhost the counters seems to be coming fine. Test and testvm are guests on the local machine where as Win8 and Ubuntu* are remote URI's connected

Hello. Package Manager reports (with a green checkmark) that I have java-1.6.0 installed on my machine (running Cent 5.3), but it seems to not be running. I used http://java.com/en/download/help/testvm.xml and got "Something is wrong. Java is not working." Perhaps I'm confused on which program I need to use java-coded apps. PM lists this app as "OpenJDK Runtime

Hallo, I have one ups with snmp and any ups without snmp. Shutdown works while network online. But some batteries are empty, so that the communication break early. Howto force shutdown if nut-snmp Communications lost? My 1. suggestion was option DEADTIME, but seem to be information only. (s. below) Any suggestions? The last way would be a ugly cronjob (like: ping || shutdown). regards Heiko

Background: ---------- I'm trying to debug a two-node pacemaker/corosync cluster where I want to be able to do live migration of KVM/qemu VMs. Storage is backed via dual-primary DRBD (yes, fencing is in place). When moving the VM between nodes via 'pcs resource move RES NODENAME', the live migration fails although pacemaker will shut down the VM and restart it on the other node.

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t
