No idea, in general I'm going the other way and fighting with getting connections INTO a VM. :-( > 2) Does KVM support multiple subnets? If so how do you specify the IP > address of a KVM subnet? Yes, take a look at the qemu docs. I haven't done it in over a year and one quick try didn't work, so I'll leave you with that, it certainly can be done. > 3) Does KVM support shared directories (i.e. host directories that can be > mounted as partitions in the VM)?

I've decided to hold off on KVM for a few months at least and stick with VMware. In fact I think I'm going to buy a VMware Workstation license when my trial license expires. The raw performance of KVM is better than VMware if you don't use any virtual IO and it's integrated into the Linux Kernel so it's worth keeping an eye on. However it's very immature. It has almost no tools and those that are there don't work very well. On the other hand VMware is very easy to configure and use. VMware is not integrated into Linux so it's a less convenient then it could be but it's still way easier to use then KVM in it's current state. By the time Fedora 10 comes out I'm hoping that KVM will have reached the usable state. |
