[Xen-users] kexec for domU

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

I've searched in a couple of places, but have yet to find a conclusive answer 
for this question: is kexec supported for domU kernels, yet?  I saw a couple of 
developer threads about possible implementation, but I tried it in SLES 11 
(2.6.32.13-0.5-xen) and I get an error:
Invalid memory segment 0x2000 - 0x595fff

I was wondering if there's something that needs to be done for kexec to work in 
domU, or if there is some other functionality similar to kexec for reloading 
domU kernels on-the-fly.  Obviously the boot time of domU is usually faster 
than server hardware, so reloading the kernel on the fly may not have the same 
benefits it does for physical systems, but I've run into some situations 
recently where loading it on the fly would be nice.

Thanks,
Nick
