RHEL 5 x64 guest VM can’t connect to network

9 08 2010

A customer’s freshly built guest RedHat 5 virtual machine (built from scratch, not cloned from a standard template) could not connect to the network, although all of the settings in the usual places seemed legit (/etc/sysconfig/network, /etc/sysconfig/network-scripts/ifcfg-eth0, /etc/resolv.conf).  Pinging anything except for the local address resulted in “Destination host unreachable.”

After playing around with re-adding the vNIC, and trying the alternative e1000 driver, I finally came across a community post that seemed to indicate the virtualization options in the standard RHEL install don’t play nice as a guest OS configuration running on VMware.  I had the customer look for processes having to do with KVM/Xen – he found that the Xen packages were installed and xend running.  Uninstalling those packages and killing the Xen process restored networking immediately!

Thank you so much….this fixed me up too. I just had to stop the xend service.

Thanks a lot. I was about to dig into data center switches thinking networking broke 🙂
