[Xen-users] How to know which interface DomU sees the Vif device
Is there a way to dinamically know on which network interface domU sees the Vif Dom0 "gives" to them. Ex: on Dom0: Vifname: vif111.0 on DomU: vif111.0 on network interface : eth0 Best Regards, Diego Dias _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Run "xm list" and see which domU has that ID. In the domU side, vif111.0 will be eth0, vif111.1 will be eth1, and so on. Another method to look (which is especially useful if you''ve changed the interface name) is something like this: # xm list Name ID Mem VCPUs State Time(s) Domain-0 0 2046 2 r----- 1700592.7 ubuntu-test 231 128 1 -b---- 26724.9 # xm network-list ubuntu-test Idx BE MAC Addr. handle state evt-ch tx-/rx-ring-ref BE-path 0 0 00:16:3E:63:2E:90 0 4 11 1297 /1296 /local/domain/0/backend/vif/231/0 # xenstore-ls /local/domain/0/backend/vif/231/0 (selected output only) bridge = "br6" domain = "ubuntu-test" handle = "0" frontend = "/local/domain/231/device/vif/0" vifname = "u-test-eth0" -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
