First create UUID by uuidgen(1): # uuidgen 4c90eb5a-adee-11e5-a747-001b2157b424 Insert the UUID to your VM config (see also /usr/local/etc/xen/vm-<VMNAME>.cfg): uuid = "4c90eb5a-adee-11e5-a747-001b2157b424" Run the VM: # xl create name.cfg Check by xl list: # xl list -v # xl list -l Your patched result is here: [root@nas4free-xen ~]# xl list -v Name ID Mem VCPUs State Time(s) UUID Reason-Code Security Label Domain-0 0 4096 4 r----- 202.8 00000000-0000-0000-0000-000000000000 - - nas4free 4 2048 2 -b---- 51.1 00000000-0000-0000-0000-000000000000 - - >> xnb device performance is terrible. >> (it eats 100% CPU on intr while transferring via bridged 10GbE) > > I haven't seen this, but I'm not surprised (I also don't have a 10GbE > card at hand right now).

I feel UUID is very small thing than performance 70% drop down via xnb. Regards, -- Daisuke Aoyama
