Has anyone found a solution?
I am having the same problem with other modern Linux distros, both with moving VMs and creating new VMs. I have tried the following and every one has failed with a "CPU has been disabled" message.
Move a working Xubuntu 12.04/32 from an XP-Pro host to Win7-Pro/64.
Move a working Xubuntu 12.04/32 from an Win7-Premium/64 to Win7-Pro/64.
Move a working Centos6.4/32 from an Win7-Premium/64 to Win7-Pro/64.
Create a new Xubuntu 12.04./32 VM using install ISO on Win7-Pro/64 host.
Create a new Centos 6.4/32 VM using install ISO on Win7-Pro/64 host.
Create a new VM and boot Centos6.4/32 live CD (ISO) on Win7-Pro/64 host.
When I tried
Create a new VM and boot Fedora19/32 live CD (ISO) on Win7-Pro/64 host
it kernel panic'ed while still in text mode. Along the trace back were the routines "identify_cpu" and "identify_boot_cpu."
I was able to do the following:
Move a working Ubuntu 10.04/32 from an XP-Pro host to Win7-Pro/64.
Move a working Win2000-Pro from an XP-Pro host to Win7-Pro/64.
Create a new VM and boot Fedora13/32 live CD (ISO) on Win7-Pro/64 host.
Create a new VM and boot Fedora15/32 live CD (ISO) on Win7-Pro/64 host.
I am using VMware Workstation 6.5.
The XP machine is a core2-duo laptop.
The Win7-Premium/64 machine is i7-2620Q laptop.
The Win7-Pro/64 PC is Dell Precision M6700 with an i7-3540M CPU.
On the M6700, initially VT, VT for direct I/O, SpeedStep and Execution Disable were all enabled in the BIOS. I tried disabling SpeedStep and Execution Disable and still got the problem.
