Hi All,
I'm facing some strange behavior with an skew in the system clock.
The hardware is a Dell PowerEdge 2950III, running two instances of
FreeBSD 7.0-RELEASE-p5 - amd64 over an ESXi hipervisor.
To both were allocated 4 processors and 4 GB of RAM, and dmesg for
both are identical.
I'm using clockspeed to synchronize the clock, but just one of
them is delaying the clock a lot.
The hardware clock is ok as far as the other virtual machine.
Where should I start to investigate?
