Hello
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 ?
How many ESX hosts? did this occur on all of them, or one of them?
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
http://www.vmware.com/support/vsphere4/doc/vsp_esxi41_u1_rel_notes.html
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.
