Virtual Machine Startup and Shutdown Behavior – Proxmox VE

For my link archive as this is configured per VM on the VM level which is different from for instance ESXi: [WayBackVirtual Machine Startup and Shutdown Behavior – Proxmox VE

Some useful commands for Proxmox high IO troubleshooting

Posted by jpluimers on 2018/02/13

After trying to move an operating system from one disk to another, Proxmox stalled the console and ended up in a really high I/O delay.

These commands helped me finding out what was wrong:

apt-get install iotop
iotop
ps -aux | grep usbbackup
ps -aux | grep rsync
zpool status
lvscan
qm list
qm unlock ###
qm stop ###

Somehow Proxmox was thinking the VM ### was still in use, but on Linux level it wasn’t:

# lvscan
ACTIVE '/dev/pve/swap' [8.00 GiB] inherit
ACTIVE '/dev/pve/root' [27.75 GiB] inherit
ACTIVE '/dev/pve/data' [62.04 GiB] inherit
ACTIVE '/dev/pve/vm-###-disk-1' [40.00 GiB] inherita

Is memory ballooning a thing from the past or still current?

Posted by jpluimers on 2018/02/02

I wonder with the current memory pricing and amounts of memory that host machines have: is memory ballooning a thing from the past?
