I don''t think you want to do that. dom0 is intended to be lightweight so as to leave as many resources as possible for your VMs. For example, your VMs will are only able to use what''s left of your memory, so we try hard to keep dom0''s memory usage to a minimum. In your case, dom0 is taking about 550 megs, leaving your VMs about 15.5 gigs to use.

actly my scenario is i am testing network driver for our 10G NIC card. for that i have inserted our 10G card in xenserver machine & installed our driver in order to test that need to send heavy traffic from physical host (xenserver) to peer(linux machine). in that case if i send heavy traffic host is getting hang. for that purpose i want to giv more memory & cpu to dom0 . thanks balakrishna.

Heh, fair enough :-) In which case, if 752M is enough then: xe vm-memory-dynamic-range-set uuid=<uuid> min=752MiB max=752MiB otherwise, edit /boot/extlinux.conf to bump up the dom0_mem to a larger number, then reboot. You may have to do the above command once you''ve rebooted. For more CPUs, you''ll need to try the beta of 5.6-FP1, which has some fixes for multi-vcpu dom0.
