CentOS6 virtio?
by Lars Hecking 01 Feb '12

01 Feb '12

Are there any updated instructions for installing Windows virtio drivers on a KVM Windows XP vm under CentOS6? The virtio .iso directory structure is slightly different from what is described in the RHEL6 virtualisation manual, and when I attempt to install e.g. the viostor driver, the device manager cannot find anything better than what is already installed. I tried each of the Wlh/Wnet/Wxp/XP directories.

Updated kvm kernael and now some guests are hung
by James B. Byrne 01 Feb '12

Earlier this evening I updated our CentOS-6.2 kvm virtual host to kernel 2.6.32-220.4.1.el6. After rebooting three guests are hung. I cannot establish connections via the network (no route to host) and the virtual console is unresponsive. On two of them I was able to initiate the login process but after the password prompt the system no longer responded. On the other the system hung when I tried to run the vi editor. The console display on each of the affected guests shows a long list of hung tasks: task jbd2/dm-0-0:384 blocked for more than 120 seconds . . . task jbd2/dm-3-8:838 blocked for more than 120 seconfs task master:1226 blocked for more than . . . task miniserv.pl:1248 blocked task pickup:29136 blocked The lists on each guest vary somewhat but share most of the same processes being blocked. One has a postmaster task that does not display on any of the others. I can recover from this but I want to get these guests restarted if I possibly can. Is there a way to do this? What would cause the problem? -- *** E-Mail is NOT a SECURE channel *** James B.
