Windows 7 KVM install runs unbelievably fast on SL 6 ( alpha 3) vs F14 with the
most recent libvirt stuff :

[root@fedora14b ~]# rpm -qa|grep libvirt
libvirt-python-0.8.7-1.fc14.x86_64
libvirt-0.8.7-1.fc14.x86_64
libvirt-client-0.8.7-1.fc14.x86_64

Boris.
P.S. It happens no matter of pre-install loading Virtio SCSI driver, which is also
possible  only on SL6 via virtio-win.1.1.16.noarch.rpm.

Fedora 14
- We have 79 open bugs, 9 of which have fixes in awaiting updates.
- 1 bug has been closed in the last week
- Virt-preview has been opened for Fedora 14, more details below

Fedora 15
- Upcoming Deadlines:
  2011-01-25  Feature Submission Deadline (2 Weeks!)
  2011-02-08  Feature Freeze--Planning & Development Ends
  2011-02-08  Branch Fedora 15 from Rawhide-- Branch Freeze

  2011-05-10  Fedora 15 Final Release
- Feature submission deadline is fast approaching, let's get those feature
  submissions done.

  == Virt Preview Repository ==
  The virt-preview repository is now active for F14 users wishing to run the
  latest F15 virt packages on their stable F14 systems.  F13 virt-preview users
  will still get the latest F14 packages.  For details on how to run enable 
  virt-preview, please see:
  https://fedoraproject.org/wiki/Virtualization_Preview_Repository
  Also note that virt-preview for F14 and later releases will live on the new(ish)
  repos.fedorapeople.org site.

  == Bugs of importance: ==
- 662380 Encrypted disks do not work
  Using virsh to create the encrypted disk, resulting disk is unusable.

- 655280 libvirt does not support vendor/product based USB device
  passthrough with QEMU

- 656943 KVM guest crashes if vmware vga option is used
  Reports of qemu crashing when a vga option is passed, using debian guests

- 589130 USB disk not marked as removable
  USB Mass storage devices are not marked as removable to a guest.
  Bug has been filed upstream as well there is some debate as to what is

SL6 = Scientific Linux 6?

And you're saying that Windows 7 is much faster on SL6 than on Fedora 14?

Not sure what 'Virtio SCSI' is.

Are virtio-blk and virtio-net drivers installed in the Windows guest?

What does the libvirt XML for this guest look like (from both SL6 and
Fedora 14)?

Installation itself . Packages deployment phase is much faster on SL 6 ( alpha 4),
even if I don't pre-load viostor.sys ( option working only on SL 6 )

Yes.


Please, view for details :-

You don't have to reboot the box to look at the xml configs.  On the vm host machine just look at/copy the VM config files in /etc/libvirtd/qemu/ (or something like that, I'm going from memory).

Probably cache related. In RHEL6 we default to cache=none, not so in
Fedora. Use 'virsh edit' to stick <driver name='qemu' cache='none'/>
in your <disk> block, and restart the guest. Newer virt-manager versions
also allow setting this in the UI.

I just set IDE Disk1 "cashe mode" none  before install.

*********************************************************************************
Post installation procedure for W7 (x64) & Rawhide Libvirt on F14
*********************************************************************************
1. Original setup on IDE device.
2. Shutdown
3. Add fake.qcow2 disk AS "Virtio"
4. Add CDROM virtio-win-1.1.16.iso
5. Load KVM
6. Update broken SCSI Driver ( in  "Device Manager" ) via attached RH's CD
7. Shutdown
8. Remove fake.qcow2 disk
9. Remove IDE boot up device, say /dev/sdb9
10. Add "Virtio" boot up device - same /dev/sdb9
11. Load KVM with Virtio boot up device.

SL 6 allows to load viostor.sys from floppy virtio-win-1.1.16.vfd
during install and detect "Virtio" defined boot up device.
F14 loads driver , but fails to detect boot up "Virtio" device in installation phase.

fake.qcow2 has nothing to do with performance issue during install on F14.

A change in the command-line parsing code in qemu-img causes
virt-make-fs to break (because of a latent bug in virt-make-fs).  Here
is the upstream fix:

http://git.annexia.org/?p=libguestfs.git;a=commitdiff;h=eda9826d25336bcf661700270c580d4d62128750

I haven't (yet) backported this to F15.
