Re: [Vserver] CentOS RPM's

I know Daniel has the fedora kernels, and I've been scouring his rpm repository to find the centos ones with no luck (plenty of util-vserver rpms, but no kernels). I had the thought that the vserver stuff might already be in the kernel (long shot i know, but anythings possible) so I downloaded the util-vserver rpms and tried them, to no avail of course :) The problem with the CentOS kernel is that it's really old and it would require major surgery in order to get any sort of recent Linux-VServer version on there. I've been playing with the idea of providing more recent, vanilla kernel RPMs too, but nothing has come out of that yet, mostly because the userspace matches the old kernel. So in order to get a recent kernel working nicely, you'd probably need to update at least udev and mkinitrd. If you take these from FC6, you need several more just because of the dependencies of the FC6-RPMS. But I didn't try it (read: rebuilding them and `rpm -i --nodeps` them) since I can't risk it ATM. Another option/possibility could be to use CentOS-5 with a (very probably heavily patched) 2.6.18 kernel which is now in beta since RHEL5 has been annouced last week or so. So at least the user-space should be much more recent.

This is actually how Solaris 10 zones work. In a Solaris 10 zone the filesystems /usr /bin /lib and so on are read-only loop-back mounts to the host OS. It makes the guest a lot smaller as a result. Pretty much most of the overhead of a guest (zone in Solaris terms) is the local files in writeable filesystems to ensure OS stability (eg /var/sadm for package maintenance). You don't have to worry about patching each guest because each guest is using the host OS; patch the host, reboot the guest and it's automatically patched. Yes, this requires native OS support (eg the patch utilities need to know that a guest exists and so updates it's package state files; the patch _contents_ would appear automatically as a result of the loopback mounts; it's merely the package state files that need updating). On Solaris not even that is necessary - the package mgmt tools can handle the update of already updated files (e.g. on read-only mounted NFS-volumes) since ages cleanly.

Then you can use localhost as usual (as hostname) and it should word. Yes, I've also done that in another vserver running Postfix + amavisd, which needs to run 127.0.0.1 on ports 10024 and 10025. But I also take note of Herbert P's previous comment to the effect that this may not be entirely safe with the curent networking code (or least that is how I understood it - I can't find that message now to check). Possibly it may be safe enough if done in one vserver, but not in more than one? I fear we are mixing here two independent things: Hostnames and IP-Adresses. 1) Your vserver has no lo Interface, where 127.0.0.1/8 resides. If I understand correctly, there some compatibility hack, that using the IP-address 127.0.0.1 is mapped transparently to another IP address. 2) The localhost entry in /etc/hosts simply maps the hostname localhost not to 127.0.0.1 as in 99.99% of all other setups but directly to another IP address. This won't work in 100% of all cases but in 99.9% (at least in my limited experience with vserver). If you specify 127.0.0.1 you are directly using the IP address, no address resolving involved. If you specify localhost or hostname.example.com, the host forst resolves that name through whatever means (/etc/hosts, DNS, ...) and uses the IP address is gets back from there.
