qcow2

I did a P to V for a windows machine that created a 175GB vhdx file and then when converting the vhdx file to qcow2 it now shows as 1TB, this makes no sense? The following command is what I used to convert the file: qemu-img convert -O qcow2 DELLM4400.vhdx DELLM4400.qcow2 -p

I recently reinstalled Proxmox on my system, and prior to the reinstallation, I had an OMV (OpenMediaVault) virtual machine (VM) running on a 4TB HDD (with 1.5TB of total storage in use). However, after reinstalling Proxmox, I encountered an issue when attempting to mount the disk again using...

Hello! For some reason, when I'm trying to convert a RAW disk, which is stored on zfs-local, to QCOW2, the format dropdown list is inactive. But if I try to move (Move Disc button) the disk to remote storage (SMB share), the dropdown is active. It seems like I've missed something during the...

Hi Everybody, a few days ago my pair of USB drives running my hypervisor (lesson learnt SATA SSDs on their way) crashed and have been corrupted. I have been able to access the NVME drive that the VMs ran on. This drive is intact I think, I have been able to access the qcow2 files from it and...

Hi, I want to migrate form HyperV to Proxmox but keep my VMs. After some reading I found out that you can export the VMs from HyperV, convert them to qcow2 with Starwind V2V and continue to use the virtual hard disk in proxmox. After doing so I copied the filename.qcow2 file in the root...

I have some VMs on AWS that are running some very old applications that I'd like to move to Proxmox. I don't have a good way to reinstall/recreate the apps running on those VMs. We're talking code that's like 15 years old and the developers are long gone and I have no one that supports these...

Hi there, I have just finished setting up my second homelab host and come to the horrible realisation that my 2 x 2TB and 4TB disks are all LVM and have running VM's on. I tried to take a snapshot, only to realise that I cannot make a snapshot due to it being LVM on the disks. I would like to...

Using libvirt, I am creating VM on Proxmox with Scaleway. I have an ansible file that create a VM name CentOS_Base, the most important commands are: # Downloading a CentOS-7-x86_64-GenericCloud-1809.qcow2 curl https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1809.qcow2 #...

Moin, aktuell habe ich das Vergnügen vmWare Maschinen auf PVE zu migrieren. Alles in Allem funktioniert das auch, die Hardware wird "umgebaut" und die Treiber greifen auch. Mir stellt sich nur eine Frage: Meine lieben externen Kollegen (ein Systemhaus in NL) hat überhaupt keine Lust, mir die...

Hi I've just read this interesting blog article on jrs-s.net (he have a lot of great articles on ZFS by the way) on the topic of qcow2 vs zvol I/O performance. The interesting part was that fine-tuning the qcow2 cluster_size to match the record size ot the underlying zfs dataset could...

Hi! Please tell me how works VM snapshots in PVE? 1. I create snapshot (disk type qcow2), do some changes on disk, and snapshot size - 0 (screenshot). 2. How creates RAW-image snapshot (backend ext4) during backup VM with type "snapshot"?
