By default, solaris will only let you add 255 IP addresses to an interface. You’ll know you hit the limit when you get an out of buffer message when you try to add your next one. In Solaris 2.5, you’re pretty much stuck with this limitation. In solaris 2.6 and higher, you can run the followng to up that limit as high as 8192. Past 8192, you’ll need to add another interface.

/usr/sbin/ndd -set /dev/ip ip_addrs_per_if 8192

I do a lot of work with MythTV and find it invaluable to run changes and latest builds inside a virtualization platform like VMWare or KVM. When using KVM through virt-manager in Ubuntu Hardy Heron, you don’t have an option to add a soundcard to a virtual machine. To get sound to work though, all you need to do is start the virtual machine from the command line and provide the -soundhw option like so.

kvm -m 1024 -soundhw all /home/jason/MythBuntu-1.img

Where -m is the amount of memory allocated to this vm.
