hi guys

I want to deploy the virtualization on gentoo . and I have finished
deploying the kvm kernel gentoo-linux-2.6.20-r8.

but how about the next steps?
anyone has the  documents about it ?

I didn't found any useful  information  about it on gentoo .

thanks in advance ~!

I think all current KVM activity on Gentoo is on bug #157987.¹

I tried it a while back on amd64 without luck. It might work now but I haven't 
really tried since I installed Xen instead.

hi Sune

I'm sorry to heard about this  -_-!..

It seems that I can't enjoy the kvm on gentoo right now ?

I had read some docs about kvm,openvz ,xen  and qemu.

I thought kvm is suit for me , but right now , I should choose another
way...............

You personal opinion , for the virtualization on gentoo and the Guest OS is
linux ,which maybe are other distributions , which kit is more performance
and stable?

thanks~~~

i recommend xen, performance is quite good, installation is easy, and heavy 
development makes it a good candidate imho.

For the moment I use Xen too and am quite happy with it. Though I just got 
another system with Intel VT support so I might want to try out KVM again at 
some point.

i'm going to go a little deeper into KVM rather 
soon as well - especially where my new hardware 
arrived just yesterday :D
however, until that, I was using linux-vserver 
and VMware in quite success so far ;)

hi Christian

I am going to run more than 5 guest os on on server , so maybe VMware is not
suit for me ＠_@

and when you finish the kvm in gentoo on your new PC , please just let me
know , I want to know some details :)

Thanks in advance and have a good luck~~~

it seems like you want os-level virtualization aka linux-vserver and openvz

no overhead, very easy deployment...

that is, when you run guests which are using the host kernel, implying you run 
a linux guest. here I'd definitely recomment you to use linux-vserver/openvz 
over any other technique as you won't need any kind of paravirtualization - 
or at least *usually* won't need.

Here in our company I've set up 7 mac-mini's with 2GB RAM each serving 5 guest 
nodes to simulate the production environment. quite fun ;)

for my home, i also want to try out other OSes aswell, like win32, so there 
I'm giving kvm a try (asap) and maybe can help pushing the ebuilds into the 
tree ;)

Christian Parpart.

It just means that it currently isn't available in the main repository.
You can still install the userspace tools manually, get an ebuild
from the referenced bug or even write your own (that's what I did).

I assume the main reason why it hasn't been added yet is because most
people wait for the kvm support to be merged back into qemu,
unfortunately there is no deadline for that (I'd guess they want to
fix the gcc-4 problems first).

thanks guys

I'm installing openvz now , but how to configure the openvz kernel configure
file for myself requirements?

When I just changed the cpu type in original configure file which was
downloaded from the OpenVZ.org .
and almost of drivers had be marked Modules by default in it .

but when I use the new openvz-kernel to boot up my computer , it displays
can't mount the "root"
and the root is not a block device (0,0)

but when I configure the kernel by hands , in the other words , it's that I
cancel all the drivers that I don't need , only choose the ones I want , and
include them in kernel ,not by Modules . But when I make the new kernel it
throw out many errors , almost of them are saying some xxxxx is not defined
in xxxxxx

who has any ideas about it ?

Thanks in advance~~~

AFAIK isn't it possible to build OpenVZ in-kernel. Choose to use OpenVz as 
modules (pay attention for getting everything related to OpenVZ).

If this won't fix your problem, please copy and paste the shown messages.

I have solved the problem , i download the latest configure file for the
openvz.org

and the new kernel is working now . I'm reorganizing the partitions of my
harddisk for the multi-OS :)

It IS possible to build OpenVZ in-kernel. But you have to modify 
edit /etc/conf.d/vz not to load modules.

Is the compilation of OpenVZ now also possible in the development version?
AFAIR last time I've compiled a new kernel version with OpenVZ not all new 
features could be built in-kernel.

I know that it was working in the 2.6.8-stable version of OpenVZ, as I've 
helped in fixing it (because it wasn't possible to compile it in-kernel).

TIA,
Steffen

I'm running my servers with 2.6.18-028stab027 without kernel - modules. Didn't 
test newer versions by now because it's stable ;-)
