I ran in some problems though and it took quite some time to make it work...
We still run quite a lot CentOS6 and Windows 2008 R2 virtual machines.
Both OS'es have networking issues after cloning. This meant I had to change the configuration in a lot of VM's.
- The issue in CentOS6/RHEL6 is described in this forum message. Timothy's answer will make it work. http://forums.veeam.com/vmware-vsphere-f24/rhel6-surebackup-t11681.html#p63750
- Windows 2008R2 gives problems if you use VMXNET3.
Look at this Veeam KB for a solution: http://www.veeam.com/kb1570
I didn't install the patch but switched the vNIC to E1000, because of the age of the patch and I read some reports this caused BSOD's.
VMware KB: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1020078
If you revert to E1000, look out for this issue if you're not running the latest VMware patches.
Virtualization is so simple, eh?
