Vmware Tips and Troubleshooting for trixbox

Running trixbox versions 2.3 (CentOS 5.x) and higher seems to have a much higher resource load when using Vmware causing audio skipping and time sync issues, here are a few fixes for these issues:

1. Set vmware processes to run with a higher priority:
Install Process Explorer and turn on VMware with the trixbox image running, then run Process Explorer and just scroll to the bottom of the list of processes and find the vmware.exe and vmware-vmx.exe processes. Click on each one and click Process, Set Priority, High or Real time from the pull-down menus.

Also if you have dual CPU or Dual core, you can try using Process Explorer to set the vmware processes to only use 1 CPU.

2. Set kernel boot parameters in grub for better vm compatibility:
login to your trixbox vmware install with putty or winscp and edit the boot loader (nano -w /boot/grub/grub.conf) and move down to ~line 16 which begins with the word "kernel." Edit that line so that it looks like the following and save your change (Ctrl-X, Y, then Enter). Then reboot your system (shutdown -r now). HINT: Everything after "noapic" is new stuff to be added, and it all must be appended to the end of the existing line:

kernel /vmlinuz-2.6.18-53.1.4.el5 ro root=LABEL=/ acpi=off noapic nosmp nolapic clock=pit
