Issue #2747 has been updated by James Turnbull. Target version set to Facter - 1.6.0
---------------------------------------- Bug #2747: the virtual fact and xen http://projects.reductivelabs.com/issues/2747 Author: seph seph Status: Accepted Priority: Normal Assigned to: Category: library Target version: 1.6.0 Keywords: Branch: Testing with 1.5.7, though trunk looks about the same. The xen detection is fairly broken. As is commented in the source file, both domU and dom0 have the /proc/sys/xen/independent_wallclock which means everything detects as a domu. Futher, /sys/bus/xen is only on my dom0 machines and the order of the if statements is wrong. A related, but possible different bug is that reading /proc/xen/capabilities requires root permission. I don't think facter should require root, but maybe people disagree. I see many ways to fix this: * You could require root, and check the contents of /proc/xen/capabilities. * You could check for some /proc files that seem to only be present in dom0 * You could check for daemons that only run on dom0 * You could use compiled code to probe the cpu I opted to check for various files in /proc. I tested this on ubuntu with xen 3.3 and xen 3.0, which is all I have easy access to. Patch attached, and new code below: <pre> if Facter::Util::Virtual.xen? if FileTest.exists?("/proc/xen/xsd_kva") result = "xen0" #elsif FileTest.exists?("/proc/xen/xsd_port) # result = "xen0" elsif FileTest.exists?("/proc/xen/capabilities") result = "xenu" #elsif FileTest.exists?("/proc/sys/xen/independent_wallclock") # result = "xenu" end end </pre> -- You have received this notification because you have either subscribed to it, or are involved in it.
