>Is there any known issues when trying to run CentOS (x86 or x64) on a fresh install of vmware 4.1? >Details as to why I am asking are here in the CentOS forums: https://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&order=DESC&topic_id=28521&forum=39 Vmware, no. I have been using it for many release including yours for some time and I only use x64. The only difference is the hardware, that's a newer box than I have at any location and its amd, mine are all Intel. ESXi doesn't emulate a consistent proc, it passes it in. If the underlying hardware is problematic so is the vm. I didn't bother to check, but I would assume that platform is supported for RHEL 5 but possibly the combination is bad. My only two suggestions: 1. I wouldn't run asterisk in a vm if my life depended on it, tried many times and it always came around sooner or later to remind me it didn't want that malarkey. 2. Slap your 299.00 down on a single incidence at vmware, you'll almost feel ripped off on how fast you will likely get the right answer. That's a big company dealing w/ very elaborate and large setups, someone will have been there and done that, I can assure you. Email back your reso, I am curious to know. jlc
