I'm running all in one juno setup. I'm doing some scale tests, wherein I could spawn 500vm's ( cirros images ). I get errors when I try to spawn multiple vm's only. In my script each user spawns 16vm's. When my script tries to go over say 4 users I get the below errors. Although, if I do it incrementally one or two users at a time it works well. Kindly let me know if any other logs are required.

I also see errors from libguestfs when its checks if it can resize the image. DEBUG nova.virt.disk.api [-] Unable to mount image /var/lib/nova/instances/ec5f5973-a4f3-4755-a70c-b2d880e4ebbf/disk with error libguestfs installed but not usable (/usr/bin/supermin-helper exited with error status 1. To see full error messages you may need to enable debugging.

ANother error during that time frame that I can see but not sure if its related: 2015-04-13 16:01:35.718 7977 ERROR nova.utils [-] Could not remove tmpdir: [Errno 16] Device or resource busy: '/tmp/tmp4EuiGA

Kindly let me know if anyone has faced the same and any pointers are appreciated.
