Centos and xen network bridge issue
Hi All, We have a single Centos 5.11 server running a xen hypervisor that went down hard after an extended power outage this weekend. I'm mostly familiar for KVM as that is the majority of what our guests run under and have tried getting up to speed on xen bridging to no avail. The problem is that after the xen server spun back up, the previously defined xen bridges were lost. I've

Xen Dom0 network fails to start at boot
I have a server running Centos 5.2 as a Xen host. A problem that's shown up recently is that at boot, the dom0 interface eth0 doesn't come up properly, with the result that the host is only accessible via remote console. If I execute 'service network restart', eth0 comes up normally, with an IP address and the correct routing. Three guests have been created via virt-manager

Hi all, Has anyone seen this before? I''m running a CentOS 5.3 with xen 3.0 and the server has been running fine for a long time.
