Slow datastore, although I would have expected it to timeout?

Was this deleting the snapshot, or creating the snapshot?

Did you have the quiesce option selected when taking the snapshot? On slow datastores or on VMs with very high I/O rates it can take some time quiesce.

Don't know on the slow install - what kind of datastore device? Local drive? SAN? RAID? If RAID what level? SATA device? SCSI device? Need a bit more info... As mentioned by hanccocka a slow datastore could acount for either problem, though I wouldn't expect it to affect apprciably the time to create a snapshot so long as you are not quiescing the machine before taking it.

Please uncheck "snapshot the virtual machines's memory" , uncheck "quiesce guest file system". when you take the snapshot.

If you turn off this option "quiesce guest file system", your operating system is only crash consistent.

This is a workaround.
