Web Hosting Talk : Web Hosting Main Forums : VPS Hosting : cannot update kernel in VPS

[hpham]

I could update to the latest kernel in dedicated server to 2.6.18-53.1.13.el5xen, but could not do it in vps. After running update, there is no new kernel. The kernel is still 2.6.18-53.1.6.el5xen.

This is yum config, can you tell me why the kernel could not be updated

# cat /etc/yum.conf

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

You need to ask your host to upgrade the kernel as its not possible to do it inside a Xen VPS

I just checked yum info, and it found new kernel, but could not update

# yum info kernel-xen

The main node is updated already

# uname -a
Linux server-name 2.6.18-53.1.13.el5xen #1 SMP Tue Feb 12 13:33:07 EST 2008 x86_64 x86_64 x86_64 GNU/Linux

So now, how to update kernel for vps?
Thank you.

you can't update VPS's kernel. VPS use the kernel that installed on the main node

[keywolf]

Yes the VPS will use whatever Kernel the Host node is using, In the Case on Xen and OpenVZ the host controls the kernel.
