hmm,

this sounds to me a bit if a suboptimal vCPU setup / Gentoo build environment 
is used in PV. 

i do a lot of compiling on source based distros like Gentoo, *BSDs etc. and i 
hate all the full VM stuff from VMware, KVM/QEMU etc. because it is 
significantly slower - especially under any others / parallel VMs load on the 
metal. So i'm wondering too....ß)

But did not tried PVHVM yet byself.

Could someone explain this deeper?


just my .02$
best regards,


niels.
