Using commands from this page: I've been able to clean up all cgroups for the container ID. Going to /sys/fs/cgroups, and running this line gets rid of all cgroups: find <container id> -depth -type d -print -exec rmdir {} \; Then I have found that the network interface stays configured on the...

Hello, One of our hosts is not cleaning up the cgroups for shutdown containers, and it prevents them from starting again. Here is a snippet of the log file I obtained by starting the container with: /usr/bin/lxc-start -F --logfile=/root/135.log --logpriority=DEBUG -n 135 lxc-start 135...

Hi, I am trying to test Snap applications inside an Ubuntu 16.04 LXC container in Proxmox, and I am running into problems. I found this link: https://stgraber.org/2017/01/31/ubuntu-core-in-lxd-containers/ And it seems snapd needs "unprivileged FUSE mounts and AppArmor namespacing and stacking"'...

I'll give that a go. I think Sandy Bridge is the best fit for my hosts. I have one node that seems to be only Nehalem, so... I have found several places where they talk about using some commands to figure out the best common cpu flags for the processors in your cluster, but they require virsh...

Hello, We created a VM for Windows 7 64bit. We didn't notice that we had the VM in kvm64 default mode until everything was fully installed and running. (We usually use "host" mode, because 3 of our nodes have the same specifications.) Now, if I shut down the Windows 7 guest, and configure it to...

AFAIK, lrzip defaults to nice 19, which would explain why pxz did it faster while having a larger "user" time.

More tests, 1Gb data: ----------------------- lzop standard 560125954 real 0m5.299s user 0m4.648s sys 0m1.136s ----------------------- ----------------------- gzip standard 423726193 real 1m13.817s user 1m13.588s sys 0m2.164s -----------------------...

Some initial results with a 128Mb file (the first 128Mb of the Windows 10 qcow2 file I have): ----------------------- lzop standard 43832314 real 0m0.442s user 0m0.376s sys 0m0.112s ----------------------- ----------------------- lzop best 36883139 real 0m25.011s user...

Hi, In my experience, lrzip more often than not beats xz. If you look at the numbers above by ojaksch, lrzip made smaller files in less time. This is not a surprise, lrzip uses LZMA like xz, with a pre-optimization of chunks to increase compression. I'm going to run some numbers now with a...

Wow those are very complete numbers! I'm still working on mine (chose a very bad example, a VM that uses whole-disk encryption, going back to the beginning now). As I said, just a suggestion. Happy to do it on my own by scripting backups.

Hi, In many cases it beats gzip in compression ratio by far. Just today I converted a gzip backup to lrzip, and it went from 100Gb to 29Gb. I am going to convert an existing lzo backup to gzip and lrzip for comparison, and I will post the numbers here.

Hi, I love using Proxmox VE, and it is a remarkable product. I have a small suggestion, which could be easy to add: lrzip for Backup as a compression option. In my use, lrzip compresses quite quickly, and achieves very impressive ratios. It seems to be particularly efficient for VM images...

Hey, thanks for those details. Getting a lot further with having a test UEFI vm here. I am having problems with network connection, though. Do you know what are the options for network card? My Ubuntu MATE 16.04.1 guest VM can't make a connection through the OVS bridge, with VLAN tag. EDIT...

Oh joy! Thanks for that!

Hi, From the README in that file, it seems this line in the .conf file could be better: args: -pflash /var/lib/vz/images/7012/OVMF.fd I am creating a machine with Proxmox VE 4.2, and it seems to work fine, but it's still very early.
