한 세트의 키보드/마우스로 여러 대의 컴퓨터를 오가면서 작업하면 좋겠는 생각을 해본 적 있나요? 저는 PC를 교체할 때 데이터 백업만으로 처리하기 껄끄러운 일들을 KVM 스위치(KVM switch) 장비를 연결해서 하나의 키보드/마우스로 처리하는 모습을 본 적이 있습니다.단일 공유기로 연결된 PC들끼리는 KVM스위치를 소프트웨어적으로 구현해주는 프로그램들도 있습니다. 예전에 마이크로소프트(MS)에서 공식적으로 제작하여 배포하는 "Mouse Without Borders" 프로그램에 대해 포스팅했었는데, 이 프로그램이 그 역할을 합니다. 윈도우 PC끼리만 키보드/마우스를 공유한다는 한계점이 있지만.Synergy라는 유료 프로그램을 사용한다면 윈도우/리눅스/MacOS를 넘나들면서 키보드 마우스를 공유할 수 있다고 하는데, 이 기능을 자주 쓴다면 구매하겠지만 가끔씩 쓰는 입장에서 구입하기는 껄끄러웠습니다.이전 포스팅 말미에 Barrier 프로그램에 대해 살짝 언급했는데, 리눅스 사용 빈도가 늘어난 현재 상황에 적용하면 좋을 것 같아 설치해 봤습니다. Mouse Without Borders는 지웠어요.Barrier 최신 버전은 Synergy 1.9 버전을 fork하여 만든 프로그램이라고 하니, 기본적인 사용성은 시너지와 비슷할 것으로 예상합니다. 적당히 써보고 좋으면 언젠가는 Synergy를 구입하게 될 것 같습니다. Barrier 프로그램은 위의 Github 페이지를 통해 다운로드 받을 수 있습니다(윈도우용/맥용). 리눅스용은 배포판별로 기본 스토어에서 받을 수 있었습니다. 우분투 20.04에서는 snap 패키지로 받았어요.▲ 앞쪽의 작은 노트북에 달린 키보드/트랙패드를 이용하여 뒤쪽의 큰 노트북을 제어할 생각입니다. 듀얼모니터처럼 활용할 수도 있을 것 갈습니다.▼ 작은 노트북은 Server 모드로 세팅했습니다(키보드/트랙패드를 직접 두드리는 컴퓨터). 윈도우용 Barrier는 서버모드 설정시 bonjour라는 프로그램을 추가로 설치하라고 요구하더군요.▲ 서버 모드를 체크하면 상호작용 설정 밑에 있는 "서버 설정" 버튼이 활성화 되는데, 이걸 눌러서...▼ 컴퓨터 배치를 조정했습니다. 사진의 PC 배열 모습과 비교해보면 이해가 되실 겁니다. 서버 PC에서 마우스 포인터를 상단으로 넘기면 클라이언트 PC를 조작할 수 있는 겁니다.▲ 서버모드 PC 포함, 총 15대의 PC를 하나의 키보드/마우스로 제어할 수 있는 것 같지요?▲ 뒤쪽의 큰 노트북에도 Barrier를 설치하고, Client 모드로 세팅하면 됩니다.클라이언트 PC는 여러 대 추가할 수 있을 것입니다.개념상으로는 어렵지 않죠?하지만 장애물이 많을 겁니다. 방해요소들을 적절히 제거해 줘야 정상적으로 작동할 겁니다.▲ 일단, Server 쪽이든 Client 쪽이든 Show Log 메뉴를 통해 로그를 확인하면서 한단계씩 전진하는 것이 좋을 것입니다.▼ 저는 아래와 같은 오류들을 Log에서 봤는데요,ERROR: ipc connection error, connection refusedWARNING: unrecognised client name "블라블라", check server configWARNING:

BarrierEliminate the barrier between your machines.Find releases for windows and macOS here.Your distro probably already has barrier packaged for it, see distro specific packagesbelow for a list. Alternatively, we also provide a flatpakand a snap.Contact info:#barrier on LiberaChat IRC networkCI Build StatusMaster branch overall build status: PlatformBuild StatusLinuxMacWindows DebugWindows ReleaseSnapOur CI Builds are provided by Microsoft Azure Pipelines, Flathub, and Canonical.What is it?Barrier is software that mimics the functionality of a KVM switch, which historically would allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment. Barrier does this in software, allowing you to tell it which machine to control by moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system.Barrier was forked from Symless's Synergy 1.9 codebase. Synergy was a commercialized reimplementation of the original CosmoSynergy written by Chris Schoeneman.At the moment, barrier is not compatible with synergy. Barrier needs to be installed on all machines that will share keyboard and mouse.What's different?Whereas Synergy has moved beyond its goals from the 1.x era, Barrier aims to maintain that simplicity.Barrier will let you use your keyboard and mouse from one computer to control one or more other computers.Clipboard sharing is supported.That's it.Project goalsHassle-free reliability. We are users, too. Barrier was created so that we could solve the issues we had with synergy and then share these fixes with other users.Compatibility. We use more than one operating system and you probably do, too. Windows, OSX, Linux, FreeBSD... Barrier should "just work". We will also have our eye on Wayland when the time comes.Communication. Everything we do is in the open. Our issue tracker will let you see if others are having the same problem you're having and will allow you to add additional information. You will also be able to see when progress is made and how the issue gets resolved.UsageInstall and run barrier on each machine that will be sharing.On the machine with the keyboard and mouse, make it the server.Click the "Configure server" button and drag a new screen onto the grid for each client machine.Ensure the "screen name" matches exactly (case-sensitive) for each configured screen -- the clients' barrier windows will tell you their screen names (just above the server IP).On the client(s), put in the server machine's IP address (or use Bonjour/auto configuration when prompted) and "start" them.You should see Barrier is running on both server and clients.You should now be able to move the mouse between all the screens as if they were the same machine.Note that if the keyboard's Scroll Lock is active then this will prevent the mouse from switching screens.Contact & supportPlease be aware that the only way to draw our attention to a bug is to create a new issue in the issue tracker. Write a clear, concise, detailed report and you will get a clear, concise, detailed response. Priority

On CentOS, therefore the show cdp command cannot be used for vWAAS on RHEL KVM on CentOS. For vWAAS with WAAS Version 6.2.3x and later, there is inline vWAAS support for the OVS switch, with additional settings in vWAAS. For example 1. Install CentOS 7.2 on UCS-C240. 2. Configure OVS switch on KVM host. 3. Deploy KVM vWAAS OVAs with OVS switch on KVM host. 4. Power off the vWAAS. 5. Add two additional interfaces. 6. Using the virt-manager, map the bridge ID in vWAAS: [root@localhost kvm]# virsh edit vwaas-name Domain vWAAS XML configuration changed. 7. Using the virt-manager, edit the virtual type: virtualport type=’openvswitch’/ 8. Sample output: Traffic Interception Methods for vWAAS on KVM For traffic interception for Cisco vWAAS on KVM, you can use WCCP (WCCP GRE or WCCP L2) or Appnav. Note When you use any of the traffic interception methods for vWAAS on KVM, you must disable Generic Receive Offload (GRO) on the Cisco UCS NIC. Use the command ethtool -K nic_interface_name gro off on KVM host to disable GRO. For example: ethtool -K enp3s0f2 gro off. If you do not disable GRO, traffic is not recognized, and packets are discarded.If you upgrade the UCS NIC firmware to the latest version, you do not need to disable the GRO parameter. For more information on configuring traffic interception methods, see the Cisco Wide Area Application Services Configuration Guide. Upgrade/Downgrade Guidelines for vWAAS on KVM Consider the following guidelines when upgrading or downgrading your WAAS system with vWAAS on KVM: Cisco vWAAS on KVM is used with WAAS Version 6.2.1 and later. You cannot downgrade Cisco vWAAS on KVM or vCM on KVM devices to a version earlier than WAAS Version 6.2.1. Note When upgrading vWAAS, do not upgrade more than five vWAAS nodes at the same time

House: KVM is like the developer who builds the house but doesn’t do the interior design, while QEMU is like the interior design company that may not build the house well but does an excellent job with the décor. Thus, we use KVM to build the house (hardware virtualization, simulating CPU and memory resources) and QEMU for decoration (software emulation, simulating network cards, graphics cards, storage controllers, and hard disks). A QEMU virtual machine is a pure software implementation that can run independently without the KVM module, but its performance is lower. QEMU provides a full set of virtualization features, including processor virtualization, memory virtualization, and I/O device virtualization. QEMU is a user-space process that must call the functionality provided by KVM via a specific interface. From QEMU’s perspective, during the VM's operation, QEMU uses system call interfaces provided by KVM to configure the kernel, and KVM is responsible for running the VM in a special mode on the processor. KVM only simulates CPU and memory, meaning that a guest operating system can run on the host, but you cannot see or interact with it. So, someone modified the QEMU code, replacing its CPU and memory emulation with KVM, while leaving the network card, display, etc., to QEMU. Hence, QEMU + KVM together form a complete virtualization platform. KVM is just a kernel module, and users cannot interact with the kernel module directly. They need to use user-space management tools, and QEMU is one of these tools. KVM and QEMU complement each other; QEMU achieves hardware virtualization speed through KVM, and KVM relies on QEMU to emulate devices. For KVM, other user-space tools exist, such as libvirt, virsh, and virt-manager developed by RedHat, and QEMU is not the only option. So, the simple and direct understanding is: QEMU is a
