Note that the "supported" way in terms of hardware is via the cpuid Hypervisor present leaf and Hypervisor CPUID Information Leaf See eg http://git.annexia.org/?p=virt-what.git;a=blob;f=virt-what-cpuid-helper.c;h=3024c375cb7b71142ded2a6a5836574d5b21f2f5;hb=HEAD http://micky.ibh.net/~liske/imvirt.html But that would involve making part of facter C and would probably break jruby support, unless we used ffi somehow Paul -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Re: [Puppet Users] Facter does not recognise Xen HVM DomU
Hello Rein, Strange, my mail took 3 days to be delivered :-/ By the way, I just had a look on the tickets you mentionned. As far as I can see, they are not duplicates with mine: it's definitelyt more dom0 detection failure related, not only domU. In my case, dom0 is perfectly detected. I can't say for PV domU as I don't use them but reading virtual.rb code, I guess they'll. My problem is that xen domU detection is currently based on some /proc or /sys files presence: - /proc/sys/xen/independent_wallclock - /sys/bus/xen These pseudo files appear only in PV domU as they're kernel related. HVM DomU does not know they're running in a virtualized environment. Therefore, their kernel does not expose these pseudo-files. I made few other modifications to virtual.rb so that I can use other ways to detect xen HVM DomU (lspci, dmidecode) as it's done for other virtualisation systems (all based on this page: http://www.dmo.ca/blog/detecting-virtualization-on-linux/).

Now I wonder to know if I use the right fact ? this could be a bug, actually a missing recognition due to the difference of HVM domU (I guess).

[Puppet Users] Facter does not recognise Xen HVM DomU
Hello everyone,
While discovering puppet, I just figured out that facter does not
recognise my server as Xen HVM DomU, at least not in virtual fact:
# facter
facterversion => 1.5.1
manufacturer => Xen
operatingsystem => Debian
operatingsystemrelease => 5.0.5
productname => HVM domU
puppetversion => 0.25.4
rubyversion => 1.8.7
type => Other
virtual => physical
My dom0 is ok: virtual => xen0
The problem is that I want to use virtual fact to manage grub menu.lst
options related to xen. For the moment, I'm trying to use virtual fact.
A quick look into virtual.rb, and a dirty hack later, I can see my HVM
domU as what they are. Now I wonder to know if I use the right fact ?
Regards,
JB
Here's my diff:

end
if result == "physical"
output = Facter::Util::Resolution.exec('lspci')

output.each_line do |p|
