[Vserver] Re: vcontext: vc_create_context(): Out of memory
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 OK, thanks to your instruction, I've recompiled the kernel, switched to static context configuration, and now I'm running around 500 virtual-hosts without a hitch. However...I have no idea how I can reach to anywhere near 5000-8000 contexts... Do all the numbers below mean running 5000-8000 of chcontext --ctx command & commands directly, instead of hosting virtual-environment with different context?

Re: [Vserver] IPv6 with Bruno patch doesn't work for me
Hi Eddy, Well, I always setup IP addresses on the host, thus don't use util-vserver for configuring interfaces. In order for util-vserver to configure your interfaces you need the following file with correct content: interfaces/X/dev(content is interface name) Use interfaces/X/nodev (empty file) to tell util-vserver not to bother setting up any address on any interface (e.g. that's done by the host) If you see an error message like "Broadcast can be set only for IPv4 addresses" you will need to check with the following patch (against util-vserver 0.30.213-rc4) or ask Daniel (daniel_hozac) for help. http://people.linux-vserver.org/~dhozac/p/uv/experimental/delta-ipv6-fix01.diff Hope this helps, Bruno On Monday 26 February 2007 20:57:35 Eddy Vervest wrote: > Hi Bruno, > > After setting up the same ipv6-address on the host system it works > fine thanks for the help (and the patch in the first place)! > > The documentation on http://linux-vserver.org/IPv6 however suggest that > with version 0.30.212 it will be done all automagically when added to the > interface configuration of the vserver (like there isn't a difference > between ipv4 and 6 in configuration).

Re: [Vserver] IPv6 with Bruno patch doesn't work for me
Hi Bruno, After setting up the same ipv6-address on the host system it works fine thanks for the help (and the patch in the first place)! The documentation on http://linux-vserver.org/IPv6 however suggest that with version 0.30.212 it will be done all automagically when added to the interface configuration of the vserver (like there isn't a difference between ipv4 and 6 in configuration). With just ipv4 I didn't have to add the quest ip address to the host like I needed to do with ipv6.

Re: [Vserver] IPv6 with Bruno patch doesn't work for me
Hi Eddy, Could you provide the contents of /proc/virtnet/106/info as well as check that the address is correctly set on the host? Adding an address to a guest that is not configured on the host will just tell the kernel that whenever that address gets available the guest may also use it. (this is the same for IPv4) If both show the same address and the address is not visible inside the guest (also check with ip from iproute2 packages, though both should work and do here) then more hunting is required...

[Vserver] IPv6 with Bruno patch doesn't work for me
Hi All, After looking at http://linux-vserver.org/IPv6 I decided to give it a try, but I wasn't successfull. I used your patch-2.6.19.3-vs2.2.0.ipv6-rc13.1.diff patch and applied it (patched and compiled without errors), but no ipv6 support in my vserver. # uname -a Linux named 2.6.19.3-vs2.2.0.ipv6-rc13.1 #1 Thu Feb 22 20:59:52 CET 2007 i686 GNU/Linux >From the host using naddress doesn't show an error: # naddress --add --nid 106 --ip 2001:610:614::53/48 Adding 2001:610:614::53 , but the ipv6 address doesn't show up in the quest using "ifconfig" Adding the IPv6 specification to the interfaces directory didn't work either. Running vserver-util 0.30.212 (build from debian/sid sources). What do I do wrong?
