 On practic: this means, that need test with KVM "Hyper-V emulation" not only Windows guest, but _all_ Linux guest

_all_ Linux need read -- not only RHEL, but 
-- Debian 7.X ( kernell v3.2 with own hotfixes set) , 
-- Ubuntu 12.04 LTS ( kernell v3.2 with hotfixes)
-- Ubuntu 12.04.03 LTS ( kernell v3.5 with hotfixes)
-- Ubuntu 12.10 ( kernell v3.5 with hotfixes)
-- Linuxes with kernel v3.6 / or v3.7
-- Linuxes with latest stable kernel v3.8 ( for example Arch Linux)
-- other possible variants

Best regards, Victor Miasnikov

P.S.
  I'm personal not want, what KVM "Hyper-V emulation" initiative stopped implemented
If it work as need -- this is very good
