I've got ESXI 5.5 with currently only one VM- it's sbs2011.
Hardware is Dell t420 , Xeon e5-2420 @1.9ghz, 1 socket, 6 cores, 12 logical procesors.
For this virtual machine I've allocated 2 sockets with 3 cores, so 6 vCPUs.
This setup has been working for the last 6 Months, but since yesterday guest OS is maxing with 100% cpu. In vsphere client I can see that the gust is only using 1000MHz, from 12000Mhz available?!
How can I make the guest to use more than this?
Obviously guest is almost unusable, being so slow.
