The FAQ says to use loopback.nloopbacks to limit the number of vif''s and veth''s that show up in dom0. This no longer appears to work. Has this been remove with no replacement or has this just changed and the FAQ hasn''t kept up? -- Jason The place where you made your stand never mattered, only that you were th...

Package: xen-utils-common Version: 3.0+hg11292-2 Severity: normal After a recent etch upgrade (2.6.17, xen-3.0.2) I was unable to "xm create" until I "modprobe netloop nloopbacks=10" Error was network-bridge couln't create vif interface (backend not found). brctl addbr ... fails because of no free netloop device. passing more nloopbacks device to the module fixed the problem.

Hi list, since release 5.3 all kernels ignore options netloop nloopbacks=<n> within /etc/modprobe.conf If <n> is smaller than four there are always four vifs created. If <n> is bigger than four the appropriate number of vifs are created. Is this expected/new/feature/bug? Henry

Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp

...:ff And when I done a /etc/xen/scripts/network-bridge I have got this : Link veth0 1 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. If the loopback driver is a module, you may raise this limit by passing it as a parameter (nloopbacks=<N>); if the driver is compiled statically into the kernel, then you may set the parameter using netloop.nloopbacks=<N> on the domain 0 kernel command line.

...ing, it said maybe because of not enough available loopback devices. I think more that this had to to with the bond0 interface. However, I followed the advice, and created some files below /etc/modprobe.d with following contents: cat /etc/modprobe.d/*loop options loop max_loop=64 options netloop nloopbacks=64 Also, with the bond interface, when the ordinary network started, it created the bond0 interface, and I was able to ping it for some seconds, until xend was started, and it tried to add the bond0 to the xenbr0. when I now restart xend, I have veth0-veth63 and I have vif0.0-vif0.63.

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

When does vif0.0 get created? Is there some shell magic? I''m trying to figure out how to do a similar peth1/veth1 split for eth1. -- Nicholas Lee http://stateless.geek.nz gpg 8072 4F86 EDCD 4FC1 18EF 5BDD 07B0 9597 6D58 D70C _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I''ve recently setup a few machines with 3.2 64bit without any unresolvable problem. These machines all run pv domU''s and a view "basic" hvm domUs. As I''ve got one machine left for internal use and testing, I would like to take a look at pciback with VT-d support (bios screen shows a VT-d [enable|disable]). My question is, do I need to add patches, or use

I put this page together just so I won't spam the board anymore begging for help..lol http://bobhoffman.com/vmissue.html This shows a working effort of bonded eths, bridged into a vm, and a few other things. The only missing thing is something on the host that ends up putting the VM internet connection into some kind of limbo. Whether it is hardware related, bug related, libvirt nat
