[ovs-dev] help! usb wifi device lost, even crash!
Hi, Here some usb wifi devices connect to host through an usb hub on centos linux release 7.2.1511.

Several problems come out: a, the wifi devices will disappear after its virtual machine shutdown, only restart host it can reuse! b, even crash occurs, puzzle!

I don't think it normally makes sense to have IP addresses on the same subnet on different VLANs. If you do that, then how would the kernel know, when it sends a packet to that subnet, which VLAN to use?

[ovs-dev] [urgent] is there anyway to enable multi-vlan for on vm upon ovs ?
hi, everyone :) in my case, there is one vm for storage sharing, we name it SVM, and several VMs as testing client. for historic reasons, i can not modify the network which uses vlan upon ovs. the SVM is corresponding to vnet0, make it as trunk for tag-2 and tag-3; the VM1 is corresponding to vnet2/tag-2 and the VM2 is corresponding to vnet4/tag-3. i wanna all VMx can connect to SVM, but VMx can not communicate with each other! ==configurations== SVM's eth0: 192.168.1.1 static 52:54:01:CB:35:C4 VM1's eth0: 192.168.1.2 static 52:54:02:CB:35:C4 VM2's eth0: 192.168.1.3 static 52:54:03:CB:35:C4 Bridge "br1" Port "vnet4" tag: 3 Interface "vnet4" Port "vnet0" trunks: [2, 3] Interface "vnet0" Port "vnet2" tag: 2 Interface "vnet2" Port "br1" Interface "br1" type: internal ovs_version: "2.5.0" = but it does not work :( they can not ping through each other! i use tcpdump to monitor eth0 on SVM, and ping SVM from VM1, it said "ARP Request who-has SVM-IP to tell VM1-IP". and i use arp to add entry for each other, then it only said "VM1-IP > SVM-IP: ICMP echo request, id , seq x, length xx", but no "reply". i have got no idea about this case, i do not know i have mistaken the concept of trunk on ovs or my config is wrong :( waiting for warm-hearted response from you. regards! ___ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
