    How do I convert an IDE disk to VirtIO?

    You just saved my day! I migrated some VMs from HyperV to Prox and I had to do IDE disks for compatibility, but disk performance was crap. Now after the switch to VirtIO the disk performance on VirtIO vs IDE is double. Thanks!

    Proxmox VM shutsdown after backup

    No errors in the task area. After the backup completes successfully I had no errors. Debian version is 8. But I dont think this is Debian related since it happened with Windows Server 2012 R2 as well

    VMs not running on full Gigabit speeds?

    I managed to get full Gigabit speeds between two Windows server VMs on the host, but not faster, even though the NICs show as 10Gbits. I wiped the server completely and install HyperV with two Windows Server VMs and between them I could get 1.8Gbits average with a peak of 2.2Gbits. Because as...
