Hi, I created a Ubuntu-17.04-x64 PVHVM DomU, so I can use "xl network-attach/detach" to add/delete network interfaces, it works well.
However I wanted to restore the DomU with a different MAC address, so before saving the checkpoit file, I deleted the network interface with "xl netwrok-detach", and assigned a different MAC in the configuration file and restored the DomU: # xl network-detach ubuntu 0 # xl save ubuntu ubuntu.checkpoint # xl restore ubuntu.cfg ubuntu.checkpoint But the DomU didn't detect the new network interface. In Dom0, could see the DomU has new MAC. # xl network-list ubuntu Idx BE Mac Addr. handle state evt-ch tx-/rx-ring-ref BE-path 0 0 00:16:3e:eb:ca:67 0 1 -1 -1/-1 /local/domain/0/backend/vif/139/0 If I add network interface manually after restoring, the DomU can detect new network interface automatically. # xl network-attach ubuntu type=vif mac=00:16:3e:eb:ca:68 bridge=virbr0 # xl network-list ubuntu Idx BE Mac Addr. handle state evt-ch tx-/rx-ring-ref BE-path 0 0 00:16:3e:eb:ca:67 0 1 -1 -1/-1 /local/domain/0/backend/vif/139/0 1 0 00:16:3e:eb:ca:68 1 4 -1 529/528 /local/domain/0/backend/vif/139/1 Is it a bug?
