What is the best way to setup one linux box to listen on its serial port for incoming connections? I've done a lot of googling but I can't find the right combination of commands to actually get them to talk! My main objective is to provide a serial interface to running instances of kvm/qemu VMs which currently only have a VNC interface (...
I'm using KVM to run a Windows virtual machine on my Linux box. Networking is accomplished through a tap device, hooked into a bridged Ethernet device, which allows the Windows VM to basically appear like a separate physical computer on my network. This is pretty nice. However, my understanding is that most, if not all, wireless drivers...
I'm trying to use libvirt with virsh to manage my kvm/qemu vms. The problem I have is with getting it to work with public IPs. The server is running ubuntu 8.04. libvirt keeps trying to run it as: /usr/bin/kvm -M pc -m 256 -smp 3 -monitor pty -no-acpi \ -drive file=/opt/virtual-machines/calculon/root.qcow2,if=ide,boot=on \ -net ...
Configuring synergy for multiple computers, each with a single screen, is fairly easy. But it is not so obvious how to configure multiple X11 screens. For example, sys1, a minimac is on the right. sys1 is the server and has a single monitor (screen). To the left of sys1 is a Fedora 9 system, sys2, with two X11 displays: sys2:0.0 and s...
I have a wireless keyboard, mouse, and a monitor (with DVI and VGA) that I want to share between two systems. Ideally, I'd prefer to just hit a keystroke (e.g. scroll-lock twice) and then have all three items switch from my PC to my mac. Is there a good product for this? I know of older-style KVM switches, and I've found a few USB swi...
I have the following comparison questions of KVM, and Xen: Security (how different are KVM and Xen here?) Speed(I'm a long time user of VMWare Workstation but there I'd think the loss is around 50 % to the native speed, this is IMHO too much) Stability (do Xen and KVM differ here much?) Maintainability (how difficult or easy is ot to s...
The joys of multimonitor programming are countless, I think there are about 5 blog posts on Coding Horror on the topic alone! I often code in Windows on my main machine, and have my Mac laptop set up to the side. I use the Mac both to compile Mac builds but also as my "reference web browser". There's no KVM or anything. However a casua...
Hello, can somebody recommend me good affordable IP KVM? Like Adder. Or some articles evaluating such KVMs? My project: Provide remote support to Linux (Fedora) based software that runs on X, but without any window-manager. I know that there is Gnome vino, but it is buggy and it does not meet my needs for other reasons. I would ...
The title says it all. I'm currently setting up vmware Server 2.0 for kernel debugging with gdb ( see this setup guide ) and someone asked me why not use kvm? So I ask: kvm vs. vmware for kernel debugging / USB driver development what are the pros and cons of each? ...
¿It's possible to share a partition (or lvm volume) and using it at the same time between the host and the guest virtual machine? For example, if you have the /home in the /dev/sdf2 partition, use it inside the otherdistro vm and work at the same time, also. Thanks. ...
I am mostly interested in developing for windows (primary) and a mac. I have a normal PC and a mac mini, and I want to be able to use a single keyboard, mouse and a monitor with both. Which kvm software do you recommend? I was looking for hardware kvms but I am using a 30" lcd which is only supported by 1 belkin kvm and people report ...
My VPS provider gives me the choice between KVM and OpenVZ. What is the best choice for a VPS with 128MB or 256MB RAM? ...
I have basic idea on Kilo Virtual Machine on Mobiles , I have clear idea of how JVM works class loaders , Executable Engine,Method Area etc . Technically how KVM differs from JVM ? Does KVM increases the execution time as compared to JVM ? Any Performance Oriented difference ? Memory management Thanks ! ...
In VMs OS-provided real-time scheduling tends not to be reliable. For my application I'd like to be able to detect whether I am running on a VM or not (Linux-only). So I am looking for a nice way to detect (in C) whether I am in a virtualized environment. Depending on the VM used there seem to be various DMI and CPUID strings in use. I...
What I'm looking for is a device that does the following: One end has a male VGA and a USB cable. This end gets plugged into any pc or server device that has the correct outputs. The other end is just USB and gets plugged into a laptop cable. In between is a "something" that grabs the VGA output and can pass USB back to the target fro...
I have a server that has several virtual machines running on it. I'm trying to connect to one of these servers using Java, but it fails with "Network unreachable". The usecase is Hudson connecting to run a slave on a windows-machine. It works using python sockets, so it's quite odd. This is the network configuration on the host machine ...
Are there tools for migrating from one virtual machine type to another? E.g let's say I have some Xen virtual machine and like to make it run under KVM. I know that qeumu has tools which can be used to "migrate" such machines, but how about: Xen -> Kvm Kvm -> Xen Xen -> VMware (server?) ...
Hi all, I want list of software installed on VM's & condition is those VM's are in Offline mode not in running mode and this list should display on main OS is it possible in KVM virtualization ? any input really appriataite !!!! ...
I'm learning Java for a course this month, and this question is just one I thought of that I'd like to know. What are the main differences between these two? I know KVM is targeted for mobile devices, correct? ...
Hello everyone! I want to make a cloud computing testing environment on my in-house network. I'm using Ubuntu (just to work on; i don't want to watch Gentoo compile screens all time:) and I plan to make an Eucalyptus installation for a cloud platform. I want to get the most of my Core2Quad and Core2Duo machines:) What I need a cloud for...
