I started out using VMware Workstation 8.0:
Oracle Linux 6.1 64-bit
VMware Workstation 8.0
Win 7 Enterprise SP1 64-bit
HP ProBook 6450b 8GB memory
The installation was touch-and-go. I first encountered this problem:
VMware Workstation doesn't support the scsi_id command!
No matter how you flip the parameters, scsi_id always returns error code 1 and <nothing> to stdout. This problem is duly noted in a number of places, most notably here: http://diznix.com/tag/scsi_id/
Once I got around that, I was only able to show two out of the four /dev/asm* disks during the ASM Disk discovery process.
Then, after a number of other attempts, I caught this VMware dialog: "VMware does not support clustering." Whether that is due to a misconfiguration on my part or a limitation on the vendor's part, I don't know.
I have since swapped VMware for VirtualBox, for a number of reasons you cite.
I'm now stuck on the "remote operations" copy, but will keep working at it.
