Hello,
while in my activities to accomplish migration of a Windows 2008 R2 VM
(with an Oracle RDBMS inside) from vSphere to oVirt, I'm going to check
performance related things.
Up to now I only ran Windows guests inside my laptops and not inside an
oVirt infrastructure.
Now I successfully migrated this kind of VM to oVirt 4.1.9.
The guest had an LSI logic sas controller. Inside the oVirt host that I
used as proxy (for VMware virt-v2v) I initially didn't have the virtio-win
rpm.
I presume that has been for this reason that the oVirt guest has been
configured with IDE disks...
Can you confirm?
For this test I started with ide, then added a virtio-scsi disk and then
changed also the boot disk to virtio-scsi and all now goes well, with also
ovirt-guest-tools-iso-4.1-3 provided iso used to install qxl and so on...
So far so good.
I found this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1277353
where it seems that
"
For optimum I/O performance it's critical to make sure that Windows
guests use the Hyper-V reference counter feature. QEMU command line
should include
-cpu ...,hv_time
and
-no-hpet
"
Analyzing my command line I see the "-no-hpet" but I dont see the
"hv_time"
See below full comand.
Any hints?
Thanks,
Gianluca

What OS type do you have set for that VM? Make sure it matches the Windows

Thanks,

If I edit the VM, in general settings I see "Other OS" as operating system.
In General subtab after selecting the VM in "Virtual Machines" tab I again
see "Other OS" in "Operating System" and the field "Origin"
filled with the
value "VMware"
During virt-v2v it seems it was recognized as Windows 2008 though...
libguestfs: trace: v2v: hivex_value_utf8 = "Windows Server 2008 R2

So it seems it has been a problem with virt-v2v conversion, because if I
shutdown the VM and set it to Windows 2008 R2 x86_64 and optimized for
server and I run it, I get this flag for the cpu:
-cpu Westmere,vmx=on,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff
BTW: what are the other flags for:
hv_spinlocks=0x1fff

So it seems it has been a problem with virt-v2v conversion, because if I
shutdown the VM and set it to Windows 2008 R2 x86_64 and optimized for
server and I run it, I get this flag for the cpu:
A new virt-v2v was just released, worth testing it. It has some nice
features, and perhaps fixes the above too.
For example:
Virt-v2v now installs Windows 10 / Windows Server 2016 virtio block
drivers correctly (Pavel Butsykin, Kun Wei).
Virt-v2v now installs virtio-rng, balloon and pvpanic drivers, and
correctly sets this in the target hypervisor metadata for hypervisors
which support that (Tomáš Golembiovský).
Virt-v2v now installs both legacy and modern virtio keys in the
Windows
registry (Ladi Prosek).
-cpu Westmere,vmx=on,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff
BTW: what are the other flags for:
hv_spinlocks=0x1fff
hv_relaxed
hv_vapic
?
These are the enlightenment that allow Windows guests to run faster (hv =
hyper-v).

A new virt-v2v was just released, worth testing it. It has some nice
features, and perhaps fixes the above too.
For example:
Virt-v2v now installs Windows 10 / Windows Server 2016 virtio block
drivers correctly (Pavel Butsykin, Kun Wei).
Virt-v2v now installs virtio-rng, balloon and pvpanic drivers, and
correctly sets this in the target hypervisor metadata for
hypervisors
which support that (Tomáš Golembiovský).
Virt-v2v now installs both legacy and modern virtio keys in the
Windows
registry (Ladi Prosek).
Thanks for the info.
In the mean time after installing virtio-win on proxy host I retried with
the same version of virt-v2v provided with 4.1.9:
virt-v2v-1.36.3-6.el7_4.3.x86_64
and then selecting and injecting it in the import window and the VM
correctly starts with virtio drivers (version 61.74.104.14100) after a
reboot requested (first starts remains in black window for a couple of
minutes and then asks to restart)
It also has qxl drivers (6.1.0.1024)
But the VM remains as "Other OS" and obviously has no hv_ optimization.
I'm going to try the new version as you suggested.
It would be nice also to have virtio-scsi option and not only the virtio
option directly in import function....
BTW: I see that in case a target VM with the same name of source exists,
I'm given an error and I can't change the VM name on destination....
This seems to me a big limitation, because forces to rename the source VM
or rename a pre-existing VM at destination with the same name....

These are the enlightenment that allow Windows guests to run faster (hv =
hyper-v).
