I experience random crashes with VMWare 10.0.4 running on Windows 7 x64 Enterprise and hosting Ubuntu 14.04 Desktop x64 on my HP Z620 machine.
Basically, once in a few days guest Ubuntu suddenly becomes very slow, and in a few minutes host Windows OS slows down as well until complete unresponsiveness: pressing Ctrl+Alt+Del result in an error "Failure to display security and shut down options. The logon process was unable to display security and logon options when CTRL+ALT+DELETE was pressed. If the operating system does not respond, press ESC or restart the computer by using the power switch."
Previously, my guest system was Ubuntu 12.04 and it worked fine, the problem started to occur only after I upgraded to Ubuntu 14.04 (Linux kernel 3.13.0). It feels like guest system starves host system of some resource, but I don't see which one. Host system has 32 cores (16 with Hyperthreading), and guest system uses 16 of them.
I tried to add these lines to config.ini, didn't help:
MemTrimRate = "0"
sched.mem.pshare.enable = "FALSE"
Host system becomes responsive again if I notice the slowness early and kill guest system.
I'm attaching a log file that includes a most recent occurrence of this problem:
I started the VM, it began to copy a few files, and then everything went unresponsive. I managed to press Suspend button and the guest eventually suspended, but host OS still was unresponsive until I restarted it.
vmware.log is attached.
Any suggestions are highly appreciated.
