Hello, Requirement: I have the need to support my apps(running on a Linux VM) on different *nix hypervisors(ESX/Xen etc). I need to know on which hypervisor my app is running. I read the CPUID usage thread - http://thread.gmane.org/gmane.comp.emulators.kvm.devel/22643 but to be honest in the end I looked at http://lxr.linux.no/#linux+v2.6.34/arch/x86/kernel/cpu/vmware.c#L88 The vmware_platform() detection code is straight forward. Current-hack: As a quick hack we just grep lspci for VMware's pci-ids. Solution: I can write a bare minimal driver, check the cpu-id as VMware's balloon driver does and then emit a proc/sysfs node. The setup packages and the apps can then check for this node-string.I'm currently working on ESX and I am hoping that this thin-driver will work. Question: Q1)Is it possible to get this functionality as part of the stock kernel or is that a bad idea? I suspect there could be other users/apps who would need to know what *nix hypervisor(or a non-virtualized environment) they are running on? Q2)If this is not the right approach then can someone please suggest another approach?
