Marcus Sorensen created CLOUDSTACK-2158:
-------------------------------------------
Summary: 'userconcentratedpod_firstfit failed to find alternate
host to run VM
Key: CLOUDSTACK-2158
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2158
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.1.0
Reporter: Marcus Sorensen
Priority: Blocker
Fix For: 4.1.0
Have a cluster of 28 32 core servers. Upgraded to latest 4.1, tried to start an
existing, stopped VM. Last host the VM ran on was full, but allocator failed to
find another. So users upgrading to 4.1, using firstfit probably won't be able
to start VMs in some scenarios.
