I've narrowed it down to an issue with the "quiesced" parameter. It does not matter if the RAM is snapshotted, so I'll leave that out.
Creating a snapshot without quiescing works fine: ~ # time vim-cmd vmsvc/snapshot.create 128 TestSnap Blah 0 0 Create Snapshot: real 0m 2.07s user 0m 0.20s sys 0m 0.00s However, turning on "quiesced" will fail: ~ # time vim-cmd vmsvc/snapshot.create 128 TestSnap Blah 0 1 Create Snapshot: Create snapshot failed real 0m 16.29s user 0m 0.23s sys 0m 0.00s After this the VM will become unresponsive and the console displays lots of messages like this. task xxx:123 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this. I will install a VM with the supported tools to check that it works there. I'll file a bug report for Ubuntu's open-vm-tools package.
