CL CL It's likely that you are missing something from your /etc/modprobe.conf; CL when the kernel is installed via yum, one of the last things it does is CL dynamically generate an initrd based on your current configuration in CL /etc/modprobe.conf CL CL The modprobe.conf on my (working) FC5 guest looks like this: CL CL alias eth0 xennet CL alias scsi_hostadapter xenblk Hmmm... I had the eth0 line in both my domUs, but the scsi line was only in one. IIRC, it was missing from the one I first tried the recent update on, so that may have been it.

IIRC, the problem after the yum update was finding the filesystems. I'm guessing/hoping that the problem is the missing scsi alias in /etc/modprobe.conf (as mentioned earlier in the thread).. -- Fedora-xen mailing list Fedora-xen@redhat.com https://www.redhat.com/mailman/listinfo/fedora-xen

It doesn't seem to be working for me with fc5 either... It just so happened that there was a fc5 kernel release (2312) yesterday or today, after I got 2307 up and running. I did the yum update in the domU, but after a domU shutdown and xm create, the domU wouldn't come back up again. I don't remember the details, but the procedure above got me back in business. I'll try to remember to take note of what fails when the next update happens (If I haven't moved that domain to fc6 by then). -- Fedora-xen mailing list Fedora-xen@redhat.com https://www.redhat.com/mailman/listinfo/fedora-xen
