Yesterday all our Esx went down due to a power supply problem
All the vms went up no problem
but the vmotion on the network switch vmkernel disapear
meaning that I had to check Use vmotion on the vmkernel settings
So I had to select vmotion to due vmotion of my vms
is it normal ?
For what it's worth, this happens to me frequently (i.e., practically every time) after rebooting. Luckily, it's only a matter of checking that little box again (and I generally only have to reboot when an update requires it).
ESXi v4.1.0 - 433742
unfortunately this is a known issue with ESXi 4.1U1
vMotion is disabled after a reboot of ESXi 4.1 host
If you enable vMotion on an ESXi host and reboot the ESXi host, vMotion is no longer enabled after the reboot process is completed.
Workaround: To resolve the issue, reinstall the latest version of ESXi image provided by your system vendor.
