From: mannu on 22 Apr 2010 08:21 Hello, Is there a way to know if solaris operating system is running as a guest virtual machine on a physical host ? There is a utility "virt-what" from redhat that does the above job for linux. Is there any similar utility for solaris ? Thanks and Regards, Manish Singh.

There are several ways but the easiest is to log into the virtual (aka Solaris Zone) and run: # /usr/bin/zonename If you get "global" then you are obviously on a global zone (physical machine). If you get a hostname back, then you are on a virtual. Keep in mind that the virtual (non-global) was purposely designed to not know anything about the global. juan martinez

There are certain things that are not clear still: 1. In my solaris 8 non global zone (virtual machine), zonename command is not present. zonename command is present in the global zone (physical machine). Hence there will be difficulty to run zonename from virtual machine. 2. I need to know in general (not just confined to solaris zones), regardless of any virtualization software like vmware, xen, virtual pc, qemu, solaris zones etc,... whether operating system is running as a virtual machine on top of a physical host. Thanks and Regards, Manish Singh.

I am not aware what is ACPI strings and how to get that ? One of the ways as already been discussed is to get manufacturer list of hardwares of computer and grep for the virtual machine organization names. Issue is that how we can get list of manufacturers for hardwares of computer like cpu, disk, memory, and so on ? One more possible way is if scsi inquiry on disk gives vendor details including name of manufacturer having virtual machine organization name. I have verified this on solaris x86 virtual machine running on vm ware ESX using format command's "inquiry" menu: format> inquiry Vendor: VMware Product: Virtual disk Revision: 1.0 format> This brings up another issue, if disk is not scsi, let us say IDE, SATA or other, then we cannot do inquiry to get vendor information. Here in these cases, how to get vendor information?

On Solaris 10 and OpenSolaris you can run smbios to get this info. At least it *looks* like this info; certainly it tells you about all the manufacturer/product strings that are embedded in the BIOS. eg Solaris 10 inside VMware: % smbios|grep VMware Manufacturer: VMware, Inc. Product: VMware Virtual Platform Serial Number: VMware-56 4d 6d f3 ac d3 e0 20-df 74 70 9e 16 cf da bd VMware SVGA II -- Chris |
