[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] Do systems have to be IDENTICAL for live migration?
I have several systems running 64bit SLES11SP1. I'm trying to Live
Migrate between a couple of them and it's not working, although the same
VM will run on each one starting it manually.
The system are not identical. ïWould one expect migration to work
between these two systems? See below.
Thanks,
James
The first system is a ProLiant DL360 G6:
Proc 1:2533 MHz
Execution technology:4/4 cores; 8 maximum threads
Memory technology:64-bit capable
Processor 1 Internal L1 Cache:128 KB
Processor 1 Internal L2 Cache:1024 KB
Processor 1 Internal L3 Cache:8192 KB
Proc 2:2533 MHz
Execution technology:4/4 cores; 8 maximum threads
Memory technology:64-bit capable
Processor 2 Internal L1 Cache:128 KB
Processor 2 Internal L2 Cache:1024 KB
Processor 2 Internal L3 Cache:8192 KB
The second system is a ProLiant DL360 G5:
Proc 1:2500 MHz
Execution technology:4/4 cores; 4 threads
Memory technology:64-bit capable
Processor 1 Internal L1 Cache:128 KB
Processor 1 Internal L2 Cache:12288 KB
Proc 2:2500 MHz
Execution technology:4/4 cores; 4 threads
Memory technology:64-bit capable
Processor 2 Internal L1 Cache:128 KB
Processor 2 Internal L2 Cache:12288 KB
When I tried to Live Migrate a VM from system one to system two I got:
