it's a packager snafu.
Note:
0.10-0.3.kvm20090303git.fc11
vs:
1:qemu-common-0.10-0.3.kvm20090303git.fc11
the 1: is the epoch, which is a sorta hidden part of the version (it's a get-out clause for packagers when some stupid upstream project goes from version 0.23 to version 0.2.4 - you have to use an epoch to turn the version into 1:0.2.4 to make it work right). Epochs are a bit of an ugly hack and it's easy to forget about them when you're packaging, as this packager did

. He should have set the versioned requirement to be 1:0.10-0.3.kvm20090303git.fc11 , not 0.10-0.3.kvm20090303git.fc11 .
It's fixed up in today's update (amusingly, upstream screwed with their versioning again, so now we're up to Epoch 2 and down to version 0.9.2...). So you should be OK now.
