If your deployment uses QEMU or KVM, we recommend using the imagesin qcow2 format, with name ending in .img.The most recent version of the 64-bit amd64-arch QCOW2 image forUbuntu 18.04 isbionic-server-cloudimg-amd64-disk.img.
CirrisOS images can be downloaded from CirrOS official download page. CirrOS is very small Linux foot print and test image on Openstack cloud environment. If your deployment uses QEMU or KVM, we recommend using the images in qcow2 format. The most recent 64-bit qcow2 image as of this writing is cirros-0.3.4-x86_64-disk.img.

In this step, we'll just reduce our windows partitions directly from Windows. The resulting disk image at the end of this step will be the sum of the boot partition, the C: drive (reduced) and a leftover unused space that we will delete (by not copying it over to a new disk).
Notice that we have /dev/sda1 which is our windows boot partition of 350 MB, /dev/sda2 which is our C: partition of now 34 GB and that the total disk image /dev/sda/ is of 100 G leaving us with a bunch of space to trim.
NOTE Although the final image will be around the same size as the actual amount of data on the server, the Proxmox VE server should have enough free space to fit the total physical disk of the server unless you plan to shrink the windows disks. once migrated to Proxmox VE.
NOTE: Depending on your hardware, you may need to boot the .vmdk file using VMware Workstation or Player before moving the file to the Proxmox VE server. This allows windows to install additional drivers for the disk controller. If promoted to convert the disk to Workstation 9.x compatibility, say Yes. You won't know if you need this step until starting the Windows VM in the final step. If you get a blue screen during boot, you should try this step.
qcow2 has this nice feature where the image file only allocates the actually needed space by the virtual-machine. but how do i shrink back the image file, if the virtual machine's allocated space gets smaller?
The image will not shrink automatically, since when you delete files, you don't actually delete data (this is why undelete works). Qemu has a facility to shrink qcow2 images back, but what the utility does is really deduplicate the zeroes from the disk, leaving all other information intact. So the idea would be to:
virt-sparsify --compress fileA fileB will reduce the size of the image, however it creates the qcow2 image as another file, so you will have to rename and move things around. You cannot use --compress and --in-place at the same time. See the following link to learn more. -sparsify.1.html
I did not know that, thank you for the info, although I thought VirtIO was the fastest non-emulated driver, why use SCSI, is it slower (apologies for my lack of knowledge).
OK, I have just added a 2nd SCSI HDD in the Virsh VM (with VirtIO SCSI controller), booted the VM and made sure SCSI drivers are all good. Shutdown the VM, then change the Boot drive from VirtIO to SCSI, rebooted the VM, all good. I then shutdown, converted the qcow2 image, copied to LXD VM location (as per above), and now the Windows LXD VM boots fine, no issues.
Thanks for your help.

Create an empty qcow2 image (this will be the disk on which we'll install our OS). I typically use a 9 GB image for Windows 2008, and a 17 GB for Windows 2012 (although I think it should work with a 11 or 12 GB image). Example:
The previous steps allowed us to have Windows fully installed in a KVMvirtual machine. The last steps consist in installing Cloud-Init forWindows, a Windows implementation of the Linux basedCloud-Init mechanism. This set of scripts transforms a legacy OSimage into a ready for OpenStack image. At instantiation of a VM,Cloud-Init fetches from a meta-data server, data such as ssh publickey and hostname that allows the instance to become unique. Cloud-Initbase is Open source, and Cloudbase provides an installer on itsblog. We'll install Cloud-Init by injecting the installer that we justdownloaded. To to that, we have to follow these steps:
It's not common to have a severe bug in Ubuntu LTS, and it's even less common to have a severe data corruption bug! We are used to the idea that data is stored reliably and safely on our computers. However, for the past week, I have been pulling my hair out because of a data corruption issue, and was really surprised to discover the true cause. I have been attempting to create several Virtual Machines (VMs) to compartmentalize my essential network services, e.g. email is separated from contacts, and I decided to use virtualized QEMU instances on my Ubuntu (18.04 LTS) system. I first provisioned a Windows Server VM, which installed flawlessly on a qcow2 image on an ext4 disk. However, I ran into issues when provisioning a Linux VM with a different virtual hard drive configuration. The drive format and definition (libvirt) for the VM was:
I usually make the hard drives on my virtual machines as small as possible to save disk space on the host. I do this because it is reasonably easy to resize them at a later date (especially if you using LVM). Anyhow here is a quick guide to resizing a qcow2 disk image.
Alternatively, the hard disk image can be in a format such as qcow2 which only allocates space to the image file when the guest operating system actually writes to those sectors on its virtual hard disk. The image appears as the full size to the guest operating system, even though it may take up only a very small amount of space on the host system. This image format also supports QEMU snapshotting functionality (see #Creating and managing snapshots via the monitor console for details). However, using this format instead of raw will likely affect performance.
The procedure to mount the drive on the host depends on the type of qemu image, raw or qcow2. We detail thereafter the steps to mount a drive in the two formats in #Mounting a partition from a raw image and #Mounting a partition from a qcow2 image. For the full documentation see Wikibooks:QEMU/Images#Mounting an image on the host.
Yes I already have the node definition for server 2019 from the GitHub link you mentioned. For windows 10 I used the the David Bombal's approach. Still neither Server 2019 nor windows 10 works. Yes I converted the image using QEMU as you mentioned.
If you didn't change the storage location, they are in /var/lib/libvirt/images as you showed in your post above.
But when you create a VM and use another location for the disk, then of course it resides there - only you can
know where disks reside - right ? :) From within Windows means that once the VM is running, open the built-in
Disk Management application and extend the file system like it has to be done in Windows (as usual). Doing it
is self-explaining, for IT sysadmins at least. If you're unsure ask a Windows expert, but I'm sure you will get this
done yourself. As a little hint : You say the disks are in /virt1, which means most probably the right disk is there.
In this case the command would be sudo qemu-img resize /virt1/.qcow2 +195G.
Windows is basically the same process but I highly recommend you download the Proxmox virtio window drivers ISO and install the guest agent tools before you shut down the VM and copy over the .qcow2 image file to the new proxmox server. That way, when you the Windows image boots up in Proxmox, it will have all the drivers it needs.
Also, follow the Proxmox best guide to deploy Windows 10/11 on Proxmox. Good advice in there. And seriously match your hardware exactly to how you had it in KVM/Virt Manager the best you can. I used SATA controller, SPICE video controller with at least 128 memory, enable QEMU agent, match CPU count and memory. Windows 10 Pro fired up for me right away with no issues.
Turns out, and it appears not many people are aware of it, there's a simple command line interfaceto the Transfer VMs built into Xenserver 6.x. Using the Transfer VM on thehost (dom0), you can expose any offline VDI as a raw image over HTTP usingbuilt-in commands with no additional software to install. Then, on your clientdisk system, you simply use curl to download the disk image over thenetwork. Very simple, and no third-party tools involved. The steps involved are given below:
You may also want to zero some of the free space on your Windows disk image, totake full advantage of the compressibility of theqcow2 image format. First, in your Windows VM, download the sdelete utility from here. Then, run the following command from a command prompt in Windows:
To get started, just boot the server to the Rescue System. Then mount the remote filesystem that contains your archive (or just upload it to the Rescue System). Then start the Installimage Script (command: installimage). In the following menu, select custom_images. This will load a blank configuration, which you can customize to suit your requirements. You will also find guidelines and examples there.
For this method, just order a KVM Console via Robot. To do this, click on the correct server on your Robot account, select the Support section, and choose the server specific request "Remote console / KVM". In the comment field for the support request, insert a direct download link for the image.
To create a link for the image, you can upload your image to your preferred file hoster, webspace, Storage Box or FTP server. As an alternative, you can send us a direct download link from a foreign website, or choose an image from our mirror. (The email that we sent you when you ordered you server also contains the login details). You will also find several Windows Server images on our mirror. 006ab0faaa
