To "install" this version as a non-admin, open a command prompt, issue the command set __COMPAT_LAYER=RunAsInvoker and run qemu-w64-setup-20170131.exe from that prompt. Install in a folder where you have write permissions, like "My Documents" or something.
To try the new qlx-dod driver linked above, in order to use the driver, update' the basic windows display adapter driver and point it to the unzipped folder for the new driver. This can be found by: Right click the Start button -> Device Manager. Expand 'Display adapters' and right click on the sub entry and hit update driver.
The main area is to create VM for Windows and I already have a working pipeline where I build Windows using the qemu builder and I was wondering if there was some steps that I could automate in order to create a post-processor for packer to export a qemu VM as a LXD image.
To add e.g. 30 GB to an existing raw image usethis command:
qemu-img resize nameofimg.img +30G
In my case, the command was run instantly and it added 30 GB to my existing file, as expected. The output was:
WARNING: Image format was not specified for 'nameofimg.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
See also QEMU Emulator User Documentation > qemu-img Invocation or the man page:
man qemu-img
In my case my image was used in a Windows 10 virtual machine. In the Windows 10 VM: click Start and search "partitions" > the search finds "Create and format hard disk partitions" > which clicked opens up "Disk Management" > Right click target partition > Extend > follow the instructions to extend your partition. It's super easy.
The Azure platform service-level agreement (SLA) applies to virtual machines (VMs) running the Linux operating system only when you're using one of the endorsed distributions. For endorsed distributions, Azure Marketplace provides preconfigured Linux images. For more information, see:
When you're using a different virtualization system (such as VirtualBox or KVM) to prepare your Linux image, you might need to rebuild initrd so that at least the hv_vmbus and hv_storvsc kernel modules are available on the initial RAM disk. This known issue is for systems based on the upstream Red Hat distribution, and possibly others.
The mechanism for rebuilding the initrd or initramfs image can vary, depending on the distribution. Consult your distribution's documentation or support for the proper procedure. Here's one example for rebuilding initrd by using the mkinitrd utility:
VHD images on Azure must have a virtual size aligned to 1 MB. Typically, VHDs created through Hyper-V are aligned correctly. If the VHD isn't aligned correctly, you might get an error message similar to the following example when you try to create an image from your VHD:
In this case, resize the VM by using either the Hyper-V Manager console or the Resize-VHD PowerShell cmdlet. If you aren't running in a Windows environment, we recommend using qemu-img to convert (if needed) and resize the VHD.
There's a known bug in qemu-img for QEMU version 2.2.1 and some later versions that results in an improperly formatted VHD. The issue was fixed in QEMU 2.6. We recommend using version 2.2.0 or earlier, or using version 2.6 or later.
Calculate the required size of the disk image so that the virtual size is aligned to 1 MB. The following Bash shell script uses qemu-img info to determine the virtual size of the disk image, and then calculates the size to the next 1 MB:
The Azure Linux Agent is required for provisioning a Linux image on Azure. Many distributions provide the agent as an .rpm or .deb package. The package is typically called WALinuxAgent or walinuxagent. You can also install the agent manually by following the steps in the Azure Linux Agent guide.
If you're migrating a specific virtual machine and don't want to create a generalized image, skip the deprovisioning step. Running the command waagent -force -deprovision+user will render the source machine unusable. This step is intended only to create a generalized image.
9. IMPORTANT: When windows installation asks you to choose an HDD where Windows will be installed, choose Load driver, Browse, choose FDD B/storage/2003R2/AMD64 or x86, (AMD or x86 depends which version of windows you are installing 64 or 32 bit), click next and you will see HDD RedHat VIRTIO SCSI HDD now.
11. Optional: if you would like to use this image with the EVE RDP console, then you have to allow RDP on this Windows machine and create a user and password. In this example, we use user/Test123. Be sure that in the Windows Firewall the Remote Access inbound rules are permitted for Public access.
IMPORTANT: for compressing an image you must have sufficient free space on your EVE host, the free space must exceed the total space (60GByte in this example) of the HDD you plan to shrink. The space needed can vary but will be the total space of the disk to be shrunk plus the size of the final sparsified and compressed image. To be safe you should have double the size of the HDD you want to shrink as free space on your EVE host. In our example we needed 65Gb of free HDD space. Once this process is done, the temporary file(s) will be deleted and free space reclaimed.
The first thing you have to do is to select how you would like to install the operating system. In this case we use a Windows 10 ISO image. Select the option Local install media and choose the Windows 10 ISO.
I recently tried the upgrade to Fedora 39. Almost everything works fine, except when trying to boot a windows virtual machine with libvirt. When I try to start an old windows vm image or create a new one, the screen of the vm just stays black. I do not even get the tianocore logo when booting the vm. Note that I can create a Fedora 38 vm just fine, the issue only seems to affect windows virtual machines. Any suggestions of how to fix this problem?
The problem occurs on both of my machines where I have tried Fedora 39.
Thanks, though I think the issue here is different. The issue here seems to be affecting any vm when using UEFI with secureboot, regardless if it is a windows vm or a Fedora vm. When selecting UEFI without secureboot in libvirt, then everything seems to work. edk2-ovmf update is being worked on to fix this, in the mean time the copr works great.
Hi. I'm wondering if anyone has successfully installed Venos OS Raspberry Pi image in qemu on Windows 10. I'd like to experiment with the Venus OS GX software features connecting to my Fronius inverters before buying a RPi. I'm getting "Kernel panic - not syncing" when I start up the image in qemu. I've tried multiple images and they all do the same thing. Any advice welcome. Here's a picture of what I get.
Newer distributions have separate binaries for these two different operation modes. For example, if you just want user mode cpu emulation for X86-64 architecture, you need to use qemu-x86_64 binary and if you need whole X86-64 bit system emulation (like your PC), qemu-system-x86_64 binary must be used in commands below.
(note: creating a raw image has severale advantages: if your filesystem supports sparse files, it only uses the actually used space of your virtual disk on your physical disk.. all journalling filesystems that use inodes support that, so ext4 for example works fine. second you can easily mount it using mount -o loop at any time. however, it does not support snapshots, use qcow2 if you need snapsots or if your filesystem does not support sparse files)
now connect with your favourite vnc client to the ip of your server and install windows. you need to load the derivers from the second cdrom that is emulated. make sure you choose the correct virtio storage driver for your windows version. it may load the wrong one if you just select the root directory and let the installer search for it, resulting in an unstable windows vm
once the installation is done, shut down your windows vm. it is now time to make it autostart upon boot of your linux machine.. in order to do that i used Thomas Martin's kvm-simple-init of which i keep a local copy (dated 2016-01-23)
by default qemu uses nat-ed network, so that the vm is in its own network and the vm host acts as a nat router. if you want your vm to be part of your network like any physical machine you have connected to your swich you can use a bridged connection..
Notice you will need virtio drivers for the nic to work. you can leave the model= option away on the first boot in order to download the virtio iso and install the drivers before switching over to virtio. however, using the e1000 (default if no model is given) is not recommended for windows VM's as this model has a tendency to crash and lose connection under heavy use. I've experienced this first hand on a CCTV server that had to monitor a couple of cameras. once the nic crashes, one has to go to network settings in windows and disable, then enable the card and it will be back online. I followed the suggestions in a Proxmox forum thread and switched to virtio.
here is an example configuration for a windows 7 machine using the above mentioned init script.. if you use another init script or run kvm manually you can simply use all the cli options listed below as an example of what you might want to pass on to qemu.. also take a look at the man page it is very informative and helpful!
to my options in the above config file. keep in mind you need to stop your VM and start it again for this change to be activated.. I first removed this setting again after the update and windows 10 ran fine, but when it installed an automatic update and i accidently killed the vm during the installation it wouldn't boot anymore and it repeatedly showed a BSOD saying there was a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. at first i tried fixing my windows installation using a wind10 dvd but that was not successfull as i couldn't even boot from the dvd.. when i ran out of options i re-enabled the core2duo cpu and voilà, it bootet straight away, finished its updates and we're all good :)
