Solusvm just released new version of VPS control panel 1.2.1o which support the custom kernel under xen pv.

” PyGrub support for Xen PV.
PyGrub enables you to start Linux DomUs with the kernels that lie in the filesystem of the DomU instead of with a Kernel that lies in the filesystem of the Dom0. This enables easier kernel update from DomU.” - http://blog.soluslabs.com/

So, how to setup your pygrub in centos and debian VPS? Please follow this instruction originated from Solusvm Wiki:
Inside the Debian VPS run this:

aptitude install linux-image-2.6-xen-amd64 grub
mkdir /boot/grub
echo “(hd0) /dev/sda” > /boot/grub/device.map
mknod /dev/sda b 202 0
update-grub

That’s it…

You can have your own kernel now.

Inside the CentOS VPS run:

yum install kernel-xen grub
ln -s /boot/grub/grub.conf /boot/grub/menu.lst

Once thats done you need to check the menu.lst and make sure it matches the kernel files inside /boot:
#ls -l /boot

HVM or harware virtual machine is a platform virtualization technology that enables full virtualization using the assisted hardware from the host processors. Each HVM is fully virtualized and has a guaranteed amount of RAM, Bandwidth and Disk Space, fully isolated. You can customized your OS via VNC or our control panel in real time. The whole customization or OS installation process is done by you in a complete isolation! Normally the physical server contain only 4 ~ 5 HVM, depends on the capacity of each HVM. With this, you can even have install a virtualization platform in your HVM!

Booting ISO image form CentOS 5.5

Starting the OS customization / installation

Existing supported OS:

CentOS 5.5 32bit

Debian 5 32bit

Fedora 13 32bit

Continue to add more ISO image from different distro.

We are launching this new product line effective from 10 July 2010 to the public.

The main reason  why we launch this product line is because many customers or potential customer is looking for custom kernel when at this moment not able to implement in Solusvm.

With this new launching, customer able to customize their own VPS is real time, starting from the booting of VPS from different linux distro ISO image. Customer need to login to our VPS control panel to start this visual OS customization by launching the java base VNC viewer.  From there, customer able to customize the package that they needs in real time, which is this different from the existing VPS under OS templates format.
