I have shifted some VM's to a new server running Quantal
and have had a world of trouble. The first one was caused
by issues with an apparently compiled in path in their
apparmor version which forced VM pools to be in /srv or
similar rather than where I wanted them. For now this was
not a big issue, and thankfully the server where it would
be a big time problem (there are individual drives per
major customer or user) is Debian.
But... I still have issues. The networking has changed
considerably and although I can get my VM running, I cannot
reach it.
The new quantal machines give you something like this:
br0 Link encap:Ethernet HWaddr ****
inet addr:10.0.0.xx Bcast:10.0.0.255 Mask:255.255.255.0
inet6 addr: *****/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
p6p1 Link encap:Ethernet HWaddr ****
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
virbr0 Link encap:Ethernet HWaddr ****
inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
vnet0 Link encap:Ethernet HWaddr fe:54:00:84:3c:4f
inet6 addr: fe80::fc54:ff:fe84:3c4f/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
The VM machine has a static ip on the same network, ie 10.0.0.x. It
worked fine on the old server but is not reachable (and cannot
connect outward).
Forwarding is turned on:
cat /proc/sys/net/ipv4/ip_forward
1
The VM has
eth0 Link encap:Ethernet HWaddr ****
inet addr:10.0.0.xx Bcast:10.0.0.255 Mask:255.255.255.0
inet6 addr: *****/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
An attempt to ping from the VM to anything outside gives a "Destination
host unreachable" message.
It has been a long time since I set the old machine up, so I
may well have forgotten some step.
