set large mtu on bridged network
Hi all, In a bridged setup, how we can set a large mtu(4k) for the interface on domU? Eventhough ''ifconfig eth4 mtu 4000'' command worked in my case, whether it reflect on the actual device? Moreover I can''t set mtu for the bridge as 4k. Setting any value above 1500 mtu shows the following error, xen-152:~ # ifconfig xenbr1 mtu 4000 SIOCSIFMTU: Invalid argument So

A VPN is switched mode
Hi all, I have been using tinc successfully for a while now. However, I need to do something different from my normal setup, and i am getting the feeling I am doing something obvious wrong. What I want to do is hookup 5 distant linux routers into one bigger network, Since I need to transmit both unicast and multicast traffic, the VPN network has to be in "Mode = switch" [Assumption

XCP jumbo frames in vm
Hello all, Not sure if I am completely missing something but here goes. I have XCP 1.0 running without any issues. I have the mtu set on both the storage network, the corresponding PIF, and the VIF to 9000 and when displayed in ifconfig it shows that this is indeed true. I have several CentOs 5.6 VMs running in HVM mode (i.e. no xen kernel) which attach to the the storage network through these

[PATCH v4 0/2] v2v: -o openstack: -oo verify-server-certificate=(true|false) (RHBZ#1651432).
The first patch restricts passthrough parameters to ones matching "os-*". This was how it was documented, but not how it was implemented. The second patch is the same as v2 here: https://www.redhat.com/archives/libguestfs/2018-November/msg00187.html Rich.

[Bridge] MTU Question
I have a bridge that has gigabit interfaces. The machine in question has the fun job of being a Bridge, Firewall and SMB server. Both of the Gigabit interfaces are connected to workstations directly via Xover cable (well MDI-X to be exact). My question is, if I enable jumbo frames on the gigabit interfaces will that make any difference in overall transfer rate of the bridge? I was thinking it

CentOS, RTL8196 and jumbo frames.
Hi all, I've just upgraded my home network to a Linksys SRW2024 (with lovely vlan trunking support!) and I'm trying to enable jumbo frames. When I try to set the MTU of an rtl8169 based network card (it's a Netgear RA311), it comes up with an error stating: # ifconfig eth1 mtu 9000 SIOCSIFMTU: Invalid argument The only options it will take are 1500 or below. Does anyone know

VLANs with Xen - work with 1 Gbit, doesn''t with 100 Mbit cards?
I have a strange problem with VLANs with Xen 3.0.4. I signalled it on Xen-users list, but found no definitive solution to it. I configure VLANs so that they are available in dom0; domUs don''t know that they use VLANs. I use a stock "network-bridge" comming from Xen for setting up networking: #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge"

Shorewall and Xen with network-dummy
Hello *, I''m trying to setup Shorewall under Ubuntu 7.04 and Xen configured to use network-dummy instead of network-bridge (network-bridge seems to be buggy at the moment under Debian/Ubuntu). Is there a shorewall config example I can use in combination with network-dummy? In particular, with network-dummy there is no peth interface and the bridge include the real eth interface. I

irqbalanced on SMP dom0 ?
Hi listmembers, not a really urgent question, but i''m just curious about it: Is it advised to use an irqbalanced on dom0 when running domU''s pinned to particular cores? as an example, i''ve got a dual quadcore xen system running with domU pinned to cores 1-3 (CPU#0) domU pinned to cores 4-5 (CPU#1) domU pinned to cores 6-7 (CPU#1) so dom0 should have 100% time on

latest xen-unstable veth devices missing
Hi, I am using the latest unstable and when I boot my xen, I do not see any veth devices. This happens even after I start xend. Xend gives this message on a "xend start" SIOCSIFNAME : Device or resource busy Presumably the creation of veth and peth is failing because of this. Any suggestions -Padma _______________________________________________

Q: firewalling in Dom0 (bonding also)
Hi, the docs suggest to use firewalling in Dom0. I have a question: Dom0 sees al the interfaces, not just those considered its "own" ones. So should I set up firewalling to use/protect only Dom0''s own interfaces, leaving individual firewalls to DomUs, or should I set up firewalling on the physical interfaces (peth*)? To make things a bit worse I'' using bonding,

Re: annoying network problem

peth device
Hi I reached the conclusion that my networking problem stems from the fact that I have no peth0 device. I''m trying to locate what creates the device, but until now no success. So I have a simple question: What creates the peth0 device in dom0? TIA Paolo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com
