  1. Parallels Virtuozzo Containers Best Practices Alec Istomin, Sr. Sales Engineer

  2. Agenda • Optimize your Virtuozzo infrastructure • New Virtuozzo Server Provisioning Best Practices • Take Control of Resources Utilization • Q & A

  3. Optimize the Virtuozzo infrastructure • Configure Virtuozzo and PIM defaults • Create Container Samples: Resources (SLM), Network Settings, Templates • Create Virtual Networks • Create IP Address Pool • Create Infrastructure and Logical Folders • Connect to your AD Domain • Create and Assign Security Roles • Configure Global Backup Defaults:Storage Location, Type (Incremental) • Schedule Periodic Backups

  4. Optimize the Virtuozzo infrastructure • Linux: Maintain Local Repositories for EZ Templates • Create Linux Distributions Mirrors: createrepo, vzcreaterepo, vzpkgproxy, vzrhnproxy • Create Custom Packages Repository: createrepo • Keep Local Repositories up2date: rsync, createrepo • Configure EZ Templates: /etc/vztt/url.map, repositories, mirrorlist • Configure yum on Virtuozzo Hosts • Maintain Local Virtuozzo updates repository • Create in a Container: vzup2date-mirror, VUS (Windows) • Keep up2date • Manual Approval is Possible: <ApproveSystemUpdate> (Linux),VUS Manager GUI • Configure on Virtuozzo Hosts: vzup2date.conf (Linux), registry or GUI

  5. Optimize the Virtuozzo infrastructure • Enable scripting across environment • Linux: Use scripting over ssh: .ssh/authorized_keys2 • Windows: Use psexec.exe from Sysinternals • Maintain the text file with Server IP addresses • Run scripts on EVERY Server from a single location • Example: one-liner to install Virtuozzo updates on ALL servers: • for i in `cat /root/servers.txt `; do ssh $i "hostname;vzup2date -m batch install --self-update --loader-autoconfig"; done • for /F "usebackq" %i in (`cmd /c "more servers.txt"`) do psexec \\%i cmd /c "hostname &vzupdate /unattended"

  6. New Virtuozzo Server Provisioning Best Practices • Unattended Virtuozzo Installation • ./install -a -o --skip-reboot -k smp --lic-key XXXXXX-YYYYYY-XXXXXX-YYYYYY-XXXXXX • virtuozzo4.0_x64.exe /L"1033" /V" VZAUTOINSTALL=1 VZ=D:\vz /qr /lv C:\virtuozzo-install.log" • Unattended Virtuozzo Updates Installation • Configure Virtuozzo to use Local Virtuozzo updates repository • vzup2date -m batch install --self-update --loader-autoconfig • vzupdate.exe /unattended

  7. New Virtuozzo Server Provisioning Best Practices Scripting Virtuozzo Post Configuration • Install Virtuozzo license: vzlicload –p XXXX-YYYY-XXXX-YYYY-XXXX • Virtual networks configuration: vznetcfg • Configure container backup defaults, ie location: vzabackup --set-folder /vz/backups/ localhost Linux • Configure EZ Templates to use Local packages repository: /etc/vztt/url.map • Copy Templates metadata from an existing ‘Master’ Server: tar cfpP - /vz/template/*/*/*/config | (ssh newserver.com tar xfpv - -C /) • Cache Templates to ensure that repositories are configured properly: vzpkg create cache Windows • Copy and Deploy cached Templates net use z: \\masterserver.com\d$\vz\templates\__cache copy /y "z:\*.efd" "%VZROOT%\templates\__cache" for /F "usebackq tokens=1" %i in (`cmd /c "vzpkgls"`) do vzpkgdeploy -i %i 2>nul

  8. Take Control of Resources Utilization • Monitor your Hardware, Learn Your Peaks and Bottlenecks • PIM - Parallels Infrastructure Manager, will be renamed to PVA (Parallels Virtualization Automation) • perfmon: Virtuozzo object in Windows Performance Counters • vmstat • vzstat • vzslmutilization.sh • /proc/user_beancounters • http://cacti.net/ • Is it CPU, Disk, Network or Memory ?

  9. Take Control of Resources Utilization Start from bird’s eye view in PIM

  10. Take Control of Resources Utilization • Inspect a Physical server with high utilization • vztop; vzps axfw -E; vzstat; vmstat; vzslmutilization.sh • taskmgr.exe; perfmon.exe • vzlist -o all • Inspect an Abusing Container • vzps axfw –E CTID • Analyze Processes inside Container • strace; ltrace; lsof • Sysinternals: procexp.exe; handle.exe • Can you tell if it’s an Application Malfunction?

  11. Take Control of Resources Utilization Tune the Application Move (temporary?) to Faster Hardware Tune Virtuozzo Resource Parameters • CPU • CPUUNITS • CPULIMIT • CPUS • Disk • IOPRIO • Network • Shaping

  12. Q & A Thank You!
