The physical machine does not see the files on the VM. It just sees a big VMDK file/disk file. It's one of more big, locked file that can't be scanned anyway. DO NOT let the AV on the Host scan these files! In fact, many times, the HOSTs will not have AV at all. The guests will each run their AV (If needed).

Hey all, general AV and VM question for you. If I have a server running Hyper-V services and a virtual server inside... both running XYZ antivirus... If I a file is scanned on the VM, does that mean the physical machine will do a scan as well? Does this mean there is double the IO load on the filesystem? Obviously there would be 2x the memory overhead, 1x for the physical host running the AV client, 1x for the virtual one. But would the on-access scanner have to scan the file on both machines? Are there some AVs out there which are "VM aware" and handle this situation? Or does this just never occur, as the physical machine never really sees a file accessed on the VM? Just curious. --Matt Ross Ephrata School District ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
