As much as I’ve been enjoying 10, there is one issue, which is that I use a lot of VMs. And I didn’t notice this until it was time to run updates on the Windows & Linux VMs.
As they went to reboot the system locked up hard. Event viewer gave me this…
I tried updating one VM at a time… crash, updated my BIOS for the heck of it, crash. Downgraded from Player 7 to 6.0.1 and crash. crash crash crash!
So I had to look to the user forums where more people seem to be greiving for their Pentium 3’s with 256MB of ram. This issue was effects both Workstation & Player, as they have the same core tech. Since I’m cheap this hits Player 6 & 7. I saw this buried at the bottom of the Workstation 11 release notes (workstation & player have the same core)
Shutting down a virtual machine on a host running Windows 10 Tech Preview can cause a blue screen.
If you have Workstation installed on a host that runs Windows 10 Tech Preview, occasionally when you shut down the guest operating system in a virtual machine, the host computer might restart unexpectedly. In this case, you see the following error code on a blue screen: DPC_WATCHDOG_VIOLATION. This issue can sometimes also occur with power-off and suspend operations.
Workaround: If a newer build of Windows 10 Tech Preview is available, try updating to the newest version.
Unfortunately, a new full build isn’t expected until after the first of the year.
So there is no workaround.
A’int that a kick in the head?
One crazy thing I’ve found is that MS-DOS & Novel Netware 3.12 work fine. You can reboot/turn off/pause them without any issues. But if you think about installing NT/2000/XP or Linux onto a MS-DOS VM something that it does to the virtual hardware sets it up for the same issue where a reboot or shutdown will cause 10 to lock up.
