Hello fellow Fedora, libvirt and libguestfs users,
If you have any Windows guests, then you can help Fedora to support
Windows guests better by spending a few minutes testing the Windows
Registry feature we just added to libguestfs 1.0.75.
You will need:
- A Windows NT/200x/XP/Vista/7/... guest
- Fedora 12 or Fedora Rawhide host
- libguestfs-tools >= 1.0.75
(from updates or
http://koji.fedoraproject.org/koji/packageinfo?packageID=8391
)
- a few minutes of your time
The tests:
(1) Run the virt-win-reg commands shown in the following web page,
where "MyWinGuest" should be replaced with the name of the Windows
guest as known to libvirt:
http://libguestfs.org/virt-win-reg.1.html#examples
Do the commands run without any errors?
Does the output look sensible?
If you have several Windows guests, please try as many different
sorts as possible!
(2) Download the registry binary files and try to convert them to XML:
guestfish -i MyWinGuest --ro <<'EOF'
download win:\windows\system32\config\software software
download win:\windows\system32\config\system system
download win:\windows\system32\config\sam sam
download win:\windows\system32\config\security security
EOF
hivexml software > software.xml
hivexml system > system.xml
hivexml sam > sam.xml
hivexml security > security.xml
Do those commands run without error?
If there's an error, try adding the hivexml -k option.
Does the XML look complete? (Try running the XML through
tidy -xml -indent -quiet < foo.xml | less
)
I hope you don't find any bugs, but if you do:
Send a reply to this message, or report a bug in Bugzilla:
https://bugzilla.redhat.com/enter_bug.cgi?component=libguestfs&product=Virtualization+Tools
It's useful to include the following details:
HIVEX_DEBUG=1 hivexml regfile 2>&1 > log.out
The Registry file itself that is failing (but note that Registry
files can contain sensitive data).
It's also useful to have positive feedback ("it worked!").
Thanks for any testing you can give, and if you have any other
suggestions for handling Windows guests from Fedora, please let me
know.
Rich.
