Red Hat Bugzilla – Bug 460277
CentoOS 5.2 x86 vmware guest has problems with SCSI emulation
Last modified: 2013-02-25 11:00:10 EST
Description of problem:
CentOS 5.2 x86_64 HOST, VMware Server 1.0.6 with CentOS 5.2 x86 guests.
Problem appears from the start, adding disk drive as SCSI does not work in x86 version, but working in x86_64 version. Same problem applies to adding physical disk drive to a VMware Guest, kernel does not see the new disk drive.
Tested all kernels in updates, centosplus, dev.centos.org, and all have the same problem except the kernel-rt(realtime one) which works but does not include other features that I need.
1. Install VMware Server 1.0.6 with CentOS as host.
2. Try to install a CentOS 5[.0.1.2] as guest with scsi disk drive emulation or direct acccess to physical drive
3. First install would give you an error that no disk drive was found, and second, if CentOS is installed with ide emulation and a direct access to a physical drive would show at fdisk -l just the first drive not the second real one.
Just one working result with a non-redhat kernel
I think that this is related to the bugzilla #445095. The default kernel does not have the buslogic module enabled (and the code is broken at the moment) and vmware defaults to it. So you need to select the LSI logic in vmware. I assume the -rt kernel has a working versions of buslogic (?). Anyway, please see comment #15 and onward in that bugzilla for a workaround.
