Qemu Manager Portable WORK Download
Scarlett Gehle
Could someone help me.
I've just downloaded the portable 7.0 version, and used on a usb stick under win7. After tried to use on another pc with Win XP and letter drive changed the Manager pop up some error message box that cannot resolve the drive letter and path that was assigned to the image in the win7 pc.
Now the path is QM\images isnt it?
So only the letter is another... why qemu search the that path.
What could i do to resolve this problem i need a version that could run on every system and in a stick not installed or i am force to use the installation version.
I installed a small version of winxp in the qemu manager.I am able to run it in a Winxp computer without administrator rights.
Do you know a way of transfering files from inside the virtual machine to the physical usb drive without installing any software in the real computer ?
Qemu Manager keeps improving! Much better interface. But the speed is a still a disapointment, compared (to the times I had vmware installed) it seems like the disks loaded just like if the os was installed for vmware, it's really slugish for qemu(note I don't have the kqemu driver, because I've had problems where qemu would freeze turn into a lingering process and won't close no matter what, despite that VMWare is not portable at all, and it's a freaking huge download compared to Qemu Manager so it's an even bigger disappointment because of that!
As of 2014, if you want to get better than the 1024x768 resolution offered by the Cirrus vGPU, and you are running KVM as your hypervisor on an x86_64 hostOS platform, you should look into using the QXL vGPU driver in the guestOS, coupled with the spice-server display. This can be configured from your virt-manager GUI settings (or of course from CLI args).
In my case, I created the VM using virt-install, put the OS on the vHDD using the normal vnc-style control and the normal cirrus-vGPU. Once everything was working, and all guestOS (and hostOS) software updates had been applied, I used virt-manager to change from vnc-display to spice-graphics, and from cirrus-video to QXL-video. It also helps to add the 'channel' to your VM for spice-vdagent[d] running inside the guest, which allows you to cut-n-paste data in between guestOS apps and hostOS apps pretty decently.
Besides offering high resolutions, the QXL/spice setup was a big improvement over the Cirrus/VNC setup when watching videos in the guestOS -- I actually got some thermal-trip warnings from the CPU when attempting to watch fullscreen videos in 1024x768 Cirrus/VNC, but the laptop ran cool and the fans were quiet when doing fullscreen 1920x1080 video with the more-efficient QXL/spice option. There are limitations on what sort of installations are supported by QXL/spice, but if your system(s) can use them, they are recommended for improved 2D and video-playback. -kvm.org/page/SPICE , scroll down to "Enabling SPICE using virt-manager". I wasn't prompted to add the channel, as the page claims, but it wasn't hard to add manually. If you are working with windows-guestOSes, or having trouble with the brief instructions at the linux-kvm.org site, see here -- -space.org/page/Documentation (but beware both the wiki and the main site are WOEFULLY out-of-date with many pages from 2009 through 2012, so tread carefully). The project is actively developed, but not very actively documented.
I know it's old, but I ended up here in June 2023. I installed Windows 11 on virt-manager and Windows was unable to change my screen resolution (locked at 1280x800, impossible to change). My video is configured as virtio in virt-manager and my user has been added to libvirt and libvirt-qemu groups. But none of that helped.
Well I am now fully happy! I have just migrated all my work stuff to Devuan 3.0 and the helpful people suggested virt-manager but no guidance. I am not quite sure myself how I managed to do it but Qemu (with the front-end Aqemu) has been able to convert my .vhd into an .img - couldn't get it to run in Aqemu directly but have done so with virt-manager - the difference is unbeleivable.
I am using virt-manager with qemu/kvm and it performs excellent. Prior I was using Virtualbox but it didn't perform that good. I see now that Virtualbox can use KVM as paravirtualization. Any thoughts on this? Is it the same stuff in the backend, just different GUI just like Virt-manager is just a gui frontend?
virt-manager is a gui frontend for libvirt.
libvirt is a collection of programs that allow management of many hypervisors/virtualization providers like qemu, Xen ,virtualbox and others.
It doesn't add/change functionality of those.
Sry @jasonwyan. @Lone_Wolf thanks for the explantion. I know that virt-manager is frontend for libvirtd which in the end talks to qemu (virsh etc.). And you don't even need virsh, you can just use qemu commands... But regarding vbox, that is vbox-guest-additions vs virtio-drivers. And vbox kernel modules vs mainline kernel modules? So in the end its all about custom stuff added to kvm hypervisor and kernel. So generally speaking vbox should give more options with kvm? Internet is silent on this, no one did some comparation in performance and stability regardin use of vbox with kvm
I've previously written about using QEMU on macOS to create an Ubuntu VM viaCLI. In this blog post I'm going to describe how to install libvirt andvirt-manager on macOS to create an Ubuntu VM via QEMU from the virt-manager GUI.
What's described in this blog post was an experiment to see if it wouldwork. Running libvirt locally is very slow and not usable due to the missingsupport for the HVFHypervisor.Framework.The developers of virt-manager (Red Hat) are not testing on macOS andit will break on major updates.
Virt-manager assumes that SPICE is available and will add it to the defaultsettings. However, it's is not supported on macOS and therefore we need to change athe default values to remove all SPICE related settings:
I feel like i am missing something basic, but in virt-manager on Arch Linux after I install virt-manager, qemu and enable libvirtd, i can only see LXC. Which as far as i know, is not for local VMs, is it? Why does it not show qemu?
Noticed that the file /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so was missing so I installed** libvirt-daemon-driver-qemu-1.2.2-379.2.x86_64**. A missing dependency somewhere?
Hello,
i defined manually the user qemu as member of group root and qemu (id group 80); It worked on Opensuse 12.3.and 13.1.(tumbleweed)
I have now a new system and I have not yet be able to restore the VM.

I have never used a guest as a server.
You can start a KVD/QEMU guest with either virsh
or virt-manager. So if you wanted a server without a console ,
use virt-manager to make the VM initially, but thereafter
start it with virsh . You can then log into it with ssh if you need to manage something.
I am not sure if you have that option with Virtualbox.
QEMU/KVM can be invoked directly without libvirt, however you cannot to use tools such as virt-manager, virt-install, or virsh. Plain QEMU (without KVM) can also virtualize other processor architectures like ARM or PowerPC.
