Hi list,
I converted one old FreeBSD 4.9 box to HVM domU (with AMD-V processors,
with Intel-VT doesn't work). All works fine, but disk performance is too
poor... about 8MB/s (in dom0 i get about 40MB/s). I did some test with
VBD with file backed and LVM but performance stills poor.
Any advices?
Is possible to use blktap in this case? Any pointers?
If I use a SAN, network performance on HVM will be a problem?
What's about tgt?
I have one HVM old linux 2.4 domU and I can get far more disk troughtput
than with FreeBSD, it is normal? In this case, domU is on Intel-VT Xen
server, is Intel-VT io implementation better than AMD?
At now, I'm only testing, in the future I will need to virtualize some
old FreeBSD servers with quite great IO demand
You need to install PV (paravirtual) xen aware device drivers into FreeBSD..
I don't know if there is such thing..
