I recently applied updates to my Ubuntu 9.04 system and as usual had
to reconfigure VMware. The /usr/bin/vmware-config.pl script completed
normally (after some dicking around), and I can log into the vmware
console and start VMs, but they all have difficulty using the
bridged network (which worked before the updates). There are all set
to "connect at power on" but the guest OS says no link, and vmware
console has this event "Message from HAL: The network bridge on
device vmnet0 is not running. The virtual machine will not be able to
communicate with the host or with other machines on your network.
Failed to connect virtual device Ethernet1. " This message is in
contradiction to the diagnostic message below that "Bridged
networking on /dev/vmnet0 is running".
I did not see what version of VMWare this is, but in the past on some of
their products I have had to delete and then recreate some of the
network interfaces in the VM hardware setup (usually the VM has to be in
a powered off state).
You may be able to get away with "sudo /etc/init.d/vmware restart" or
you may need to reboot if the Ubuntu updates installed a new kernel (you
will likely have to run the vmware-config.pl script again).
I've googled around and don't see an obvious solution. Everything
appears to be working normally as the following diagnostics show:
The vmnet module is a good start. Try removing the kernel module (sudo
rmmod vmnet) and then modprobing it, see if there are any interesting
details in syslog.
If anyone has seen this before or better yet has a resolution, I'd be
very thankful.
Over the past 10 years I have seen a wide variety of issues with VMWare.
What is worrying is that I have more problems now than 5 years ago, and
many of their products that I have in production (vmware server) only
run reliably on older distros, like Ubuntu 8.04. I can only hope that
by the time 8.04 is out of support that alternatives have become capable
enough or somehow the laws of the Universe reverse and VMWare chooses to
play nice with the kernel developers... I am not holding my breath.
I wonder whether in time as os's offer a built-in vm, vmware may evolve
into a niche product. For eg. RHEL now offers kvm (about a year ago
Redhat replaced support for xen with kvm, possibly because Citrix
acquired zensource and is apparently close with MS - say in the same way
Novell with SuSE is playing nice with MS)
BTW for hands-on learning kvm I found this
http://www.telecom-lille1.eu/people/landru/viminal/index-en.html#vodka-lab.
The lab explains with clear hands on lessons COW (copy on write) file
images, network bridging and other mysteries.
These folks offer liveDVD 'learning lab environment' for ipv6,
networking, kerberos authentication, with ldap and snmp labs in the works.
It seems Telecom Lille is a French technical university. But these labs
include superb English documentation for us not so bilingual types.
