Wow - "how to set ram cpu disk ip on openvz" can be easily googled.

For your sake, I'll help you out.

First, install OpenVZ with the quick install page.

Then, download templates from https://openvz.org/Download/template/precreated.

Create a container:

/usr/sbin/vzctl create 101 --ostemplate centos

Add an IP address:

/usr/sbin/vzctl set 101 --ipadd 192.168.1.1 --save

Start a container:

/usr/sbin/vzctl start 101 

Set memory limit:

/usr/sbin/vzctl set 101 --privvmpages 256M --save 

Set disk limit:

/usr/sbin/vzctl set 101 --diskspace 5G:5G --save

Those are the basics. Use the OpenVZ wiki to learn more.

But how to take control those container, like start, reboot, etc

Is is possible to install panel like openvz web panel or proxmox on this KVM ?

noaman

I beleive the command is vzctl enter...did you even look at the wiki

noaman

@add_iT
@flamerunner already told you how to start a container....vzctl start...

Carpe

also interested in deploying OpenVZs within a KVM, so the KVM might "have" multiple timezones

Just use virtualizor free trial to set it up and you will get it going right away if you like virtualizor just pay 1$/mo for it and be happy^^

Well follow this:

yum update -y

yum install -y wget

cd /etc/yum.repos.d

wget http://download.openvz.org/openvz.repo

rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ

yum install -y vzkernel.x86_64

yum install -y vzctl vzquota

yum install -y ploop

sed -i 's/kernel.sysrq = 0/kernel.sysrq = 1/g' /etc/sysctl.conf

sed -i 's/net.ipv4.ip_forward = 0/net.ipv4.ip_forward = 1/g' /etc/sysctl.conf

echo 'net.ipv4.conf.default.proxy_arp = 0' >> /etc/sysctl.conf

echo 'net.ipv4.conf.all.rp_filter = 1' >> /etc/sysctl.conf

echo 'net.ipv4.conf.default.send_redirects = 1' >> /etc/sysctl.conf

echo 'net.ipv4.conf.all.send_redirects = 0' >> /etc/sysctl.conf

echo 'net.ipv4.icmp_echo_ignore_broadcasts=1' >> /etc/sysctl.conf

echo 'net.ipv4.conf.default.forwarding=1' >> /etc/sysctl.conf

sysctl -p

sed -i 's/NEIGHBOUR_DEVS=detect/NEIGHBOUR_DEVS=all/g' /etc/vz/vz.conf

sed -i 's/options nf_conntrack ip_conntrack_disable_ve0=1/options nf_conntrack ip_conntrack_disable_ve0=0/g' /etc/modprobe.d/openvz.conf

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

yum install -y ntp

ntpdate -u us.pool.ntp.org

chkconfig ntpd on

reboot

And install the Ovz Web Panel:

wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | sh

Use above method for my kimsufi box [Source]

Now i successfull installing it but i cannot connect to ovz side

Let see if i have ip eth0 xx.xx.xx.x2 / xx.xx.xx.xx.x6 / xx.xx.xx.x9 on KVM side node

How to assign it to each container?

Make sure the IPs are not bound to any interface and then add them to the container.

vzctl set CTID --ipadd IPADDRESS --save

Very interesting script, especially since I can't make out most of what it does starting with line 8 (first 'sed' command)… adding brief comments in it, line by line, would be very helpful (for bash newbies like me

https://github.com/jarland/ServerScripts/blob/master/vzup.sh

So simple and useful… pure genius! A couple of suggestions, though… not much hassle to add (for bash guru), but making the script much more user friendly:

• check for existing containers and start with next container id in line as default input

• change OS text input to a list select input, populating it from /vz/template/cache

EDIT: I know, I know… a couple of other things, add a web front end, and will wind up with another OpenVZ CP
