I have an i7 ASUS box, 8 vCPUs, 16GByte of memory, and Workstation 9 running on Windows 8. I come from VMware Player which had the same issues, so I wanted to upgrade to the supported product but it seems to have the same problem.
I can install and run 64-bit Linux guests, Ubuntu and CentOS. However, when I restart the VMs they fail to boot, without any visual/textual feedback. I have suspected the USB support, so I have enumerated all the configurations of enabling/disabling/filtering any of the USB devices and bridges, but the same behavior remains. I also have completely removed the USB support and same results. The behavior is always the same: I can install and use a 64-bit guest OS, but the next time I try to start it, it fails to boot without visual feedback.
Another tidbit of information, in one of the VMs I was able to successfully start and run, it went into sleep mode and resuming the VM generated a failure with a dialog that stated something like: the underlying hardware platform is different from the platform on which the VM was configured. this may lead to failures, do you want to continue. I continued and got an error saying the the XSAVE CPU instruction was not supported.
Is there any support tools that folks can point me to so at least observe the boot log to see where it gets stuck?
