I'm installing VMware Server 2.0 on an Ubuntu 9.04 system. I have an Ubuntu 9.04 guest with Bridged network interface configured.
When I try to get an address during installation, the guest fails to contact the DHCP server. NAT and Host-only networking both work fine, however.
I have a libvirt/KVM server running on Ubuntu 9.04 with a variety of instances I use for testing. I was destroying instances via virsh and occassionally, destroying one instance would take out another. Is this normal? Because it's certainly not ideal.

While there's a wide variety of private non-routable networks across 192.168/16 or even 10/8, sometimes in being thoughtful of potential conflict, it still occurs. For example, I set up an installation OpenVPN once with the internal VPN network on 192.168.27. This was all fine and dandy until a hotel used that subnet for floor 27 on their wifi.
I re-IP'd the VPN network to a 172.16 network, since that seems to be all but unused by hotels and internet café's. But is that an appropriate solution to the problem?
While I mention OpenVPN, I'd love to hear thoughts about this problem on other VPN deployments, including plain ol' IPSEC.
