CRIU is old technology like container but recently get focused on its special function; live migration on container. memory saving function itself is eligible to know this technology.
this slide is created for understand open vswitch more easily.
so I tried to make it practical. if you just follow up this scenario, then you will get some knowledge about OVS.
In this document, I mainly use only two command "ip" and "ovs-vsctl" to show you the ability of these commands.
Email and social media integration is very effective as you can have the best of both worlds. With social media, you can further define your target audience.

There are 6 creative ways in which you can achieve email and social media integration. Read on to find out more!
The document summarizes the editing process for a video project over the last few days before the deadline. It describes adjustments made to remove unflattering shots and blurry footage in response to feedback. Widescreen formatting was added to close-up shots but not throughout due to indecision. Additional filming of smoke shots caused issues integrating multiple colors. Last-minute suggestions like adding projected video behind widescreen clips were considered but cut for time. The editing was finalized by repeatedly reviewing for accuracy and getting final approval before submitting by the deadline.

This document discusses how education can help transform lives and achieve better outcomes. It presents a story of three friends over 15 years to illustrate this point. Without education, one friend remained in the same position, while the friends who pursued more education were promoted and earned higher salaries. The document encourages students to continue learning and receiving a quality education to achieve a better life. It highlights videos of motivated children discussing their dreams and efforts to realize their dreams through education, which has helped transform their lives. The document promotes striving for quality education and then helping others who lack access to it, to change the world together.
The document discusses conventions for film openings, title sequences, and how the creators of the document incorporated these conventions into the opening of their own film. Film openings aim to attract viewers and establish genre within the first 2-5 minutes by introducing characters, beginning the plot or narrative, using establishing shots and scenes, and including key credits over visuals and non-diegetic sound. Title sequences present the title, credits for production companies, directors, producers, actors, and other key roles, utilizing both visual and auditory elements. The creators' own opening was over 2 minutes, showed production companies first, included an establishing scene of the setting with added non-diegetic sound, and introduced the two main characters as the narrative began,
Food allergies are a common nutritional problem, affecting 8% of American children. Common food allergies include cow's milk, eggs, wheat, soy, fish, and peanuts. Removing allergenic foods from the diet could impair growth and development since many are nutrient dense. It is important that everyone in contact with an allergic child be made aware of the allergy for safety reasons. Skin prick tests, blood tests, and oral food challenges can help identify specific food allergies. While there is no cure, avoidance of the allergenic food and developing plans with schools and caregivers are important for management.
Dreys Productions would be classified as a small indie production company targeted towards teens due to its niche focus, as portrayed through its ident featuring graffiti-like paint splats selling the urban realism theme of the film. Chrome Entertainment would be a larger, more established distribution company suited to the film because it can reach a wider audience across genres by distributing a range of films, as suggested by its ident featuring a silhouette of city skyscrapers further enhancing the urban theme.

The document discusses various visual effects that were applied to text in a title sequence, including box blur, echo effect, fast blur, and changes in opacity. The box blur and fast blur effects were used throughout the sequence for continuity. The echo effect added a "bubble" look and brighter white color. Changing the fast blur value and opacity level alongside the effects helped the text appear minimally blurred at times and clearly in focus at others, mirroring the protagonist realizing their mental illness. Applying multiple effects rather than just one created a bigger difference in the title appearance.
This short document promotes creating presentations using Haiku Deck on SlideShare. It encourages the reader to get started making their own Haiku Deck presentation by providing a button to click to begin the process. The document is advertising the creation of presentations on Haiku Deck and SlideShare.
This document is a project report submitted by Naushad Chaudhary towards fulfilling requirements for a Post Graduate Diploma in Management. The report examines the success probability of technical analysis in the equity market. It provides an overview of technical analysis techniques like chart analysis, trend lines, support and resistance, indicators and pattern recognition. The report also includes data analysis and interpretation of technical indicators to demonstrate calls made on stocks. It evaluates the performance of these calls and concludes on the effectiveness of technical analysis.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
It explains virtualization technology, KVM How-To, RHEV introduction for users and engineers.
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). RHEV is based on KVM and includes Red Hat Subscription program. You can understand about virtualization in this document.

2. RED HAT ENTERPRISE LINUX 72
• 프로세스의 현재 상태 저장
• 이전 상태 복원 기능 (checkpoint 전으로 )
• Checkpoint 된 프로세스의 모든 정보는 하나이상의 이미지 파일로
저장됨
( 저장정보 : memory pages, file descriptors, inter-process
communication, and so on)
• 같은 시스템 또는 다른 시스템에 프로세스 복원
• 컨테이너 라이브 마이그레이션 같은 용도로 사용됨
• Tech Preview on RHEL7.2

3. RED HAT ENTERPRISE LINUX 73
• HPC 환경을 위해 개발
• 하나의 어플리케이션이 수백 , 수천 코어에 분산되어 실행되는
환경에 적합
• 특히 어플리케이션이 실패할 경우 , 전체 CPU 사용된 것이 쓸
모없게 되고 데이터도 손실되는 약점을 CRIU 로 해소
• 어플리케이션과의 호환성 검토 필요
• 초기에는 관심받지 못하다가 container migration 으로 각광
CRIU
Birth of CR
4. RED HAT ENTERPRISE LINUX 74
1) criu on command
CRIU
How to Use
2) criu in docker
- checkpoint container status
- restore checkpoint image
https://circleci.com/blog/checkpoint-and-restore-docker-container-with-criu/
5. RED HAT ENTERPRISE LINUX 75
• CRIU can only checkpoint and restore processes using inter-process
communication (IPC)
• This means that CRIU always checkpoints and restores a parent
process and all its child processes
• the PID must stay the same. A CRIU restore process fails if the
intended PID is in use
CRIU
Limitations
