Hello, I have installed cloudstack-management, cloudstack-agent(KVM hypervisor) and nfs-server at the same physical server. Then I have created virtual machines one by one in 8 parallel threads. For each thread I created shared network(VR). This server has two SSDs with ZFS filesystem. Copying files and disk speed is good enough (not only in system idle), but when I have 450 virtual machines the next one has been creating during 5 minutes, is it correct work? This time becomes too long on 200 (about a minute) virtual machines and increase on every 10 machines or so. Does anybody have any ideas how to make it faster?
Here is another question: how transaction from secondary storage to primary works. I see that images on primary are something like delta from original image (deduplicated?). Which component of Cloudstack is responsible for transfering data from secondary to primary? Thanks in advance for any ideas and info. Best regards, Dmitry
