So if I understand correctly, if i use GNBD i should not put swap.
Does iSCSI work better then GNBD and would I be able to put swap and
improve performance?

Yeah I check for VMX in the dmesg but it was not there. Also I checked
the BIOS to enable any intelVT through that, but there was none. I
want to make windows 2k3 run through xen.


Also I wanted to know if there are any good xen managment tool
available. I got enomalism. Has anyone tried this? Or is there any
other good xen management tool?


Thanks,
Naha
