Actually, there's something quite wrong with these results:

yum:
Install    172 Package(s)         
Update    2388 Package(s)         
Remove       1 Package(s)         

solv:
1564 upgraded packages
76 installed packages
31 erased packages
1 arch changes from i386 to noarch
5 arch changes from x86_64 to noarch

Downloading 1636 packages, 1812867 K

so solv is clearly missing some features.
