...e by "ovs-vsctl add-br brvlan2 xenbr3 2" Then add a port (portvlan2) to brvlan2: ovs-vsctl add-port brvlan2 portvlan2 tag=2 ifconfig vlan2 192.168.33.200 Now the problem is that I do know how to attach portvlan2 to VM. Could someone give me simple steps to setup VLANs using Open vSwitch and attach them to VMs? Moreover, the newly created bridges are not shown in XenCenter. If I use xe network-create, the newly created network can be shown in XenCenter. Is this because XenCenter uses xe command and does NOT support to show Open vSwitch? The question I wonder most is what is the di...

Hi, In XenServer5.6 FP1 beta, I have switched default bridge to open vswitch, I wonder how to use "xe tunnel-create" to create a GRE tunnel. my commands: xe tunnel-create pif-uuid=eth0_uuid network-uuid=network_created_by_xe_network_create then I got an uuid which is "access-PIF" of output from "xe tunnel-list". what should I do next? how...

Hi all, I used "net-define" to create a network to use to attach VMs to an Open vSwitch bridge. The net-define worked fine, I can see the network in "net-list" (I set it to started and to autostart) but when I try to attach a new VM's NIC to this network (via virt-manager), I'm getting the following traceback: Unable to complete install: 'Unable to add bridge vl...

Package: xcp-xapi Version: 1.3.2-14 Severity: important I chose the Open vSwitch (ovs) networking mode when I installed XCP # cat /etc/xcp/network.conf openvswitch Whenever I boot a VM, I notice that the vif interface is created (e.g. vif1.0) on dom0, and the vif is added to the ovs bridge (I can see it in the output of ovs-vsctl show) However, there is no connectivity, I ca...

Hi Folks, I have a snv_105 sxce host that I just can''t get to work as expected with crossbow + zones. My test host persephone, is a virtual machine running under VMware ESXi 3.5, with 2 virtual network cards (e1000), all on the same flat network/subnet. It started life just 2 days ago with a clean install of snv_95, and I LUed to 105 yesterday. To rule out any sharing issue, the first

I have two hosts as Xen Server named host A and host B in the same network. A VM is created on Host A. Host A and B have a shared storage using NFS. While doing migration from host A to host B, how can I see the memory pages being migrated. If I run a small continuous program on the VM residing on host A, will the migration complete first or the sript running will complete first? How can I see

...ibvirt with KVM guest machines and linux bridges. Firewall rules based on iptables and defined on the host server control inbound/outbound traffic to/from each VM. In order to improve remote administration facility and get extra services, it makes sense for us to replace linux bridges with Open vSwitch. However, the side effect is the solution's inability to filter VM traffic since it's impossible to set-up iptables rules with ovs bridges. OpenStack/Quantum circumvents this problem (no talking about performance) by setting an extra linux bridge and veth pair between the guest TAP and...

Thanks Laine, I will take a look at Open vSwitch, it looks interesting. I am a generalist, I need to know enough about a lot of things to get many different tasks done, but do not have the in depth knowledge required to "patch" anything.  If I manage to wrangle a working solution should I post it? Needless to say I would be support...
