Vmotion error on multiple VMs

Hi Folks,

is there any reason as to why when I migrate multiple VMs into newly upgraded ESXi host failed altogether with this error message ?

Failed to write checkpoint data (offset 594009, size 16384): Timeout.
vMotion migration [179830799:1379587402125979] failed: Unable to send remote call to write checkpoint data (16384 bytes @594009) to remote host <10.18.1.18>: Timeout

Does a single VM migrate?

vMotion network errors? - check vMotion network?

yes it is always loaded correctly as no changes in the network settings.

is it because that I selected all VMs in one ESX host (about 15 VMs) to be migrated at once ?

If you select 15 VMs for vMotion, only 4 can be vMotioned concurrently, and the others tasks should then be queued.

BUT, can you vMotion a single VM?

can you vMotion two VMs together?
