Virtual machine cpu throttling after Vmware esxi upgrade

[jackod]

Hi all,

I have updated one of my host in my production infrastracture to the last Vmware patchs (esxi version 5.5.0 5230635)

After that, all VM that run on this host have serious problem of cpu throttling. If they are on load the cpu go on 100% of usage and the VM not responding

I have updated the vm tools but it's doesn't solve the issue; if I migrate the machine on another host (esxi version 5.5.0 3116895) the cpu usage decrease immediately.

Which could be the problem?

Thanks in advance for support,

Jack

It will depend on a lot of factors. Is the host a part of the cluster or has reservation set.
