You're technically right, I'll message the server operator and see if he can update the available images. I don't think that the risk is exceptionally high however as OOTB with a core install there are no network services like Apache or SSH running so the attack profile would be pretty small.

Re: [ubuntu-uk] Ubuntu Server Install
Surely a machine should be provisioned with an updated install? Or am I missing something? Oooh, and come to think of it under Xen HVM the machine isn't provisioned with any kind of install. You're responsible for setting it up yourself. Of course it doesn't help with the install media is old!

Re: [ubuntu-uk] Ubuntu Server Install
I'm posting this information here just in case anyone finds it interesting. I don't have any connection to the company mentioned but as these VPSs seem pretty cheap considering they're hosted in the UK, I thought I'd share the info! The new Xen HVM provider I have been using (and this thread was in reference to) is called Damn::VPS. www.damnvps.com I can't vouch one way or the other for them (they are new and I've only just set up an account with them) but as it's only a little over six quid for a VPS with 512MB RAM, 15GB HDD 1000GB Monthly bandwidth, it's worth getting a VPS just for learning/testing.

[ubuntu-uk] Ubuntu Server Install
Hey ladies gents, I've been trying to install Ubuntu Lucid Server onto a XEN HVM based VPS and have come across a strange problem. Using the Ubuntu 10.04 i386 DVD I highlighted 'install ubuntu in text mode' and selected the 'install a server' option. I then went through the installer selecting default options (except choosing a standard partition layout instead of LVM) and finished up the installation by leaving all of the server setup options like 'setup a LAMP server' etc deselected (thus leaving only a core system install on the VPS). Upon logging into the newly installed system (and I've done this twice now) I find that the server is running a generic rather than a server kernel. Running sudo apt-get install linux-server and rebooting doesn't seem to replace the kernel either. Any ideas where I may have gone wrong? :-S Thanks in advance, Chris -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

According to the dependencies for linux-image-server it depends on a package linux-image-generic-pae which installs the latest linux-generic-pae image. Are you running the linux-image-generic or the linux-image-generic-pae. If you see the grub menu at boot up, what images are displayed in the kernel list? Is the one you want at the top? I think either shift or space key displays grub if it is not shown as the system boots. There also seems to be separate packages for kernel running as a virtual guest, linux-image-virtual. Maybe that is a more appropriate image for running on Xen, I am afraid I dont know at present. -- John Stevenson jr0cket.com leanagilemachine.com -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

I wanted the server kernel as I was worried that the generic one might have kernel preemption turned on. I'm not an expert in this, but I believe that Xen HVM (where virtualisation is done in hardware) doesn't require that the guest has a modified kernel.

Ah. In answer to my own question, it looks like the i386 server kernel
was 'dropped' in Karmic.
Note that the i386-server flavour is being dropped. I can think of no
good reason to continue to support a 32 bit server. The 32 bit
-generic kernel ought to suffice for those headless implementations
that have used the -server flavour in the past, such as home gateways.
All of the -server unique settings can be made at runtime to a
-generic{-pae} kernel, the most important of which are I/O and process
scheduler settings.

I guess that would make a bit of sense since pretty much all CPUs (if
not all new CPUs) are 64-Bit capable. Presumably if it's mission
critical then it's always an option to stick with Ubuntu 8.04 LTS on the
server for another couple of years (by which time I presume the hardware
would have been replaced with something newer or virtualised maybe?).
