I have a couple of Xen servers which can't reboot reliably - only rarely
it reboots fine; mostly, it will end up with a blank screen, and someone
has to physically reboot the machine. Not that great if you're working
remotely.
I thought a good workaround would be to use kexec when the machine needs to be rebooted. So I tried: # kexec -l xen-3.1 # kexec -eAnd xen kernel started, complaining that the dom0 kernel was not specified. So it works, kind of. So, let's add the dom0 kernel: # kexec --initrd vmlinuz-2.6.18-xen-uncomp -l xen-3.1 Invalid memory segment 0xc0100000 - 0xc034cfff Not that great. Is there something I'm missing?I tried to execute it from two machines: running a 2.6.18 dom0 kernel, and running a regular 2.6.22 kernel - both failed in the same way. kexec version I'm running is: kexec 1.101 released 15 February 2005 Any hints? -- Tomasz Chmielewski http://wpkg.org _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
