[Xen-devel] Performances compare between PV domU & HVM domU & PV-on-HVM domU
hi all
As we all know, xen currently support these three types domU mode, and every
mode has it''s own features, such as:
Advantages Disadvantages
PV: Good I/O performance Have to modify the domU kernel
Hardware Independent Can''t support windows
HVM: no need to modify kernel not good at I/O performance
support various OS include Hardware dependent(VT)
linux, windows
PV-on-HVM: Optimize the I/O Have to transplant the pv
performance with pv drivers drivers between various kernel support
various OS include versions
linux, windows
1.Are the compare right? Or where can I get the more detailed
performance compare given by the government? Specially, what about I/O
performance between PV & PV-on-HVM???
2.When I choose domU mode, what conditions should I care for?
3.Is PV can use VT hardware technology?
4.In future, which modes will become the main direction?
Any reply will be appreciated, thanks a lot.

no one want to discuss the advantages between PV domU & HVM domU?
