Use it at installation or add it after installation. To use the virtio-win drivers in vista 64-bit and later, you will need signed drivers for installation. From my reading about 32-bit vista and later, you can use unsigned drivers there. As far as I know, only redhat provides release-signed drivers via the virtio-win supplement. Those have redistribution restriction, so unless you have a rhn entitlement... The unsigned drivers themselves were opensourced. You can test-sign the netkvm (virtio net) driver, but you need to run the guest in testsigning mode to install them after the fact. I have run test-signed netkvm drivers (Sept. 24, 2009 driver release) on win7 and they worked OK, but did not extensively test them. Actually, they worked fine on all guests I tried (winxp 32-bit, vista 64-bit, win7 64-bit). Went back to e1000, rather than run the system in testsigning mode (ugly display, something like safe mode). The e1000 works fine, no hassles installing/using it under win7. Currently, the only guest I have running the netkvm driver is winxp, because e1000 was not a trivial option. Before you ask, could never get win7 to boot using the viostor (virtio blk) drivers, but could get winxp and vista to boot on them. From what I have read, the viostor drivers (Sept. 24, 2009 release) are not ready for prime time, but there were updated viostor drivers released recently that I have not tested.
