Hi Guys,
I am trying to evaluate, kvm at my work for virtual support in our product..
I had setup up a windows guest, in my ubuntu host, on hardware with Intel VT
support.
Now when I try to download a 1 GB file present, inside windows virtual
machine, using samba, from a another linux box, I get the following...
a) time when coping from windows in kvm
linux:~/tmp # time cp /media/hdisk/1GB_text.txt .
real 6m36.478s
user 0m0.060s
sys 0m8.293s
linux:~/tmp #
b) time when coping from linux native..
linux:~/tmp/tmp # time cp /media/hdisk/1GB_text .
real 0m49.501s
user 0m0.040s
sys 0m8.657s
linux:~/tmp/tmp #
So its like 50second (linux native) Vs 6+minutes(windows guest in KVM),
which is huge.
This is using user based networking, where I am just forwarding all the
netbios ports from host to guest.
Are there any links, pointers, faqs, ideas , suggestions I could try out to
increase the performance of this kvm virtual machine? Will using public
bridge (option 3), as described on page
http://kvm.qumranet.com/kvmwiki/Networking help?
