    I have only two virtual machines, doing nothing, one windows 2016 and the other one Linux, a Mikrotik virtualized router. Each one shows more than 100% in Top, but virtually nothing inside.

    SSD/NVME passthrough, support ssd/flash flag, rotation_rate=1/0

    It should be possible to set a virtual disk drive to be backed by an SSD/Flash device. Virtio SCSI with SCSI, VirtIO and SATA drives should support this. Virtual box supports this since 2014, when can we expect this to happen in PVE? According to the upstream sources this should be possible...

    I'm trying to assign 4GB of ram to a virtual machine, but after I enabled hotplug for memory and cpu, the ram that the vm sees is not 991 (actually 1GB). Before enabling the hotplug, it worked as as expected. Any ideas what's going on? I'm running proxmox 5.1-41 and the vm is running Ubuntu...
  17. Adding a route through cloud-init

    Greetings I'm testing cloud-init on a brand new Ubuntu 18.04 VM. My problem is that the IP of the VM and the GW are not on the same subnet (which is quite usual for a floating IP), so I guess the whole process of setting network fails. I can see the parameters in...
  18. Moving from Qemu KVM to Proxmox on same hardware

    I am currently running Qemu-KVM on an Ubuntu 14.04 host. Since I don't have spare hardware, I will need to backup my current VM's to restore them on the new ProxMox environment. I understood that in theory a KVM VM disk (either raw or qcow2) can be used as disk on ProxMox (5.2) too, so would my...

    Hi guys, I setup a 3-node experimental cluster with LVM on iSCSI (FreeNAS) as storage. Live migration fails when the CloudInit drive is attached but it works fine without the CloudInit drive. Is this normal? Live migration with the CloudInit drive attached gives this error...
