Its return me error virtualization support is disabled. I was tried to repair permissions in disk util but it doesn't help. Any ideas how it can be fixed ? Parallels Desktop 8
Same boat here - I reset the virtualization setting too - no effect. Reinstalled Parallels, no effect.
Looks as if the Parallels 8 kernel extension signatures are not regarded valid anymore for DP4. Console error message: "ERROR: invalid signature for com.parallels.kext.hypervisor, will not load" with similar msgs for the other Parallels kernel extensions. Apparently the modules are not listed in /System/Libraray/Extensions/AppleKextExcludeList.kext. Maybe the Parallels development team is able to suggest a workaround.
No issues here with DP4. With DP3 Windows 8.1 would trigger a kernel panic after a few seconds and under Windows 7, Chrome browsing freezes the VM. After DP4 upgrade, everything is working fine.
