Virtuozzo – VPS commands – Open VZ commands

====================
vz -> recommends ext3 file system
PIM -> IP:4643
PMC -> mangaing h/w node
PPP -> for managing a single container
All the above things need a license from parallel
====================

Templates

====================
OS template -> vzpkg (cache needs to created before creating the container)
EZ template -> points to the repository that contains packages that constitute the template
Application template -> mysql template
====================

To create a container

====================
vzctl create
the container ID > 100
32 -bit integer
ID – 0 -> h/w node
ID -1 -> service container

/etc/vz/conf -> for the sample file names (only use the main part of the file name)

vzctl set – configure the container
vzctl exec – run anything on the container
vzctl status/vzlist 101

vzpkg – for adding application templates on h/w node (/vz/templates)
– the same command can be used for installing/removing the template into a the container.

Virtuozzo – User’s guide

OS virtualization – (1-2% of is spent on the virtualization s/w)
VZFS – allows sharing of common files among containers
Hardware node & Containers

/etc/vz/vz.conf
/etc/vz/conf/
/etc/vzbackup.conf

Standard migration
vzmigrate

Zero downtime migration
vzmigrate –online –require-realtime my_node.com 101

Move the container within the h/w node
vzmlocal

Backup & restore
vzabackup/vzarestore

Reinstall container
vzctl recover -> restores the VZFS symlinks
vzctl reinstall -> creates new private area for the container, copies the old private area to /old dir
– vps.configure, vps.reinstall

Delete the container
vzctl destroy

Disabling the container
vzctl set

Suspending the container
vzctl suspend

Setting up resources
disk quotas – first level(how much files or disk space the container can use) and second level (quotaugidlimit > no of entries in /etc/passwd or group files)
Container must be restarted to come this changes into effect

vzquota – to check the status of the quota info

Cleaning up containers – to move identical files from contrainers to /vz/template/vc folder
vzcache

Linking container files with application templates
vzpkg link
vzpkglink
vzpkgls

Managing CPU – cpu share and the number of processors the node can make use of.
vzcpucheck

Network traffic
/etc/vz/conf/networks_classes – after any changes, you need to service vz accrestart
class 0 – no accounting will be performed
class 1 – defined by containers to match any IP address
vznetstat

Bandwidth management (outgoing traffic)
service vz shaperon, shaperrestart, shaperoff
BANDWIDTH -> kilobites per second
TOTALRATE -> ::

For container
RATE -> ::
RATEBOUND -> to specify if the bandwidth is limited to the RATEBOUND
====================

Monitoring tools

====================
vzstat
vzps
vzpid
vztop
vzsetxinetd

Virtuozzo networks
vznetcfg if list

vznetcfg vlan add eth0 5
vznetcfg vlan del eth0.5

Keeping system up2date
The h/w node can be updated using the normal update procedures without affecting virtuozzo
vzup2date – /etc/sysconfig/vzup2date/vzup2date.conf
vzup2date -m batch install –core
vzup2date -t -m batch install –all-os

Updating the containers
vzpkg update 101 redhat-el5-x86
vzpkg update 101
vzpkg update cache fedora-core-8-x86

Loading iptables modules
/etc/sysconfig/iptables-config
/etc/vz/vz.conf
/etc/vz/conf/.conf
