I've just switched from an MSI K8 MASTER2-FAR with dual Opteron 240s to a Tyan S2877 with dual dual-core Opteron 265s. I'm running VMWare Workstation 5.5.4 under FC6 and since the mobo/processor switch all the guest OSes get terrible performance accessing the hosts disks. I'm using Samba on the FC6 host OS for a WinXP guest which mostly just gives up after many seconds trying to read disk files. I've found lots of postings on the net about time synchronisation problems using dual-core Opterons caused by the TSCs not being synched between the processors, and I've tried restricting the guests to just a single core - but to no avail. I have not found any answers posted anywhere. Has anyone encountered this problem? If so, does anyone have a solution? TIA Dick
