Hi Yun, Thank you for your quick response.
Yes, I am using essex release. I added one line 'libvirt_nonblocking=true' in nova.conf, took a snapshot, then created a VM, it also needs a long time(about 3 minutes) during the task of 'networking' and 'spawning' -- I think this is because I was snapshoting at the same time. I am thinking whether it can get better response time if move the glance service to another server or deploy multi-node glance. I wonder whether glance support multi-nodes mode and where can I get the instruction. All help are appreciated.
