Hi there,

I have a fresh XEN - HyperVM installation.
I did this from home originaly with Local IP.

My HW Node have Internet, and my VPS had internet at that point.

Now the server is in datacenter the HardWare Node does have internet, i can managge the only one VPS i have there.

But the VPS does not have internet !

I did setup nameserver well.

Info:

HW Node IP: 72.55.164.4 / 255.255.255.224
GW: 72.55.164.1
Primary DNS server: 209.172.41.202
Secondary DNS server: 209.172.41.200

Like i said HW node have internet.
Now my VPS use the range 174.142.224.200/29

So first ip: 174.142.224.201 / 255.255.255.248
GW: 72.55.164.1
Primary DNS server: 209.172.41.202
Secondary DNS server: 209.172.41.200

FROM VPS:
sh-3.2# ping google.com -c 4
ping: unknown host google.com

ping -c 4 72.55.164.4
PING 72.55.164.4 (72.55.164.4) 56(84) bytes of data.

Restrict the platform OS usage of the ram.

title CentOS (2.6.18-92.1.22.el5xen)
root (hd0,0)
kernel /xen.gz-3.3.1 dom0_mem=2048M
module /vmlinuz-2.6.18-92.1.22.el5xen ro root=/dev

If you're just doing 1 VPS then change it to a value like 512M

BTW you are not using the default hypervisor 3.1 are you? Update it to 3.3.1 or 3.4.2 and that will improve the situation.

Hi there,

Thank for reply.

What you means when you say
"BTW you are not using the default hypervisor 3.1 are you?"

Where can i find this information, and how to update it ?

I just append
kernel /xen.gz-2.6.18-164.11.1.el5 dom0_mem=1024M
To the kernel line in grub.conf

How can i update my kernel to 3.3.1 ?
yum update only had Selinux update which is disabled.

Look at my post here

http://forum.lxcenter.org/index.php?t=msg&goto=56209& ;#msg_56209

Now there is also a 3.4.2 which is stable.

after you do it, just make sure you reboot your platform.

You can check your current version by typing

xm info

in shell. It will probably show 3.1 right now if you don't know what I was talking about.
