  1. Clusterwide VM templates

    Hi! I really love the cloud-init integration and with the templating, it's really easy to spawn new vms. However, i'm unable to create a template for the whole cluster. I'd like to have a template on some kind of shared storage (like NFS) and create full clones of this template on all nodes...
  2. cloud-init: hostname on first boot

    The wiki already mentions a problem with the cloud-init images default hostname, which should work with versions > 18.2. However, i tried latest bionic image with 18.2-27-g6ef92c98-0ubuntu1~18.04.1 and it still get's it's dhcp lease for ubuntu rather then the vm hostname (which is properly set...
  3. GUI shortcuts

    I think that i once stumbled upon a list of GUI shortcuts but i can't find it any longer (or my brain is fooling me). What i'd love is a shortcut to enter the global search field. I'm pretty sure it exists ;)
  4. ZFS fails to mount datasets

    After last update in no-subscription on one of my test servers, zfs fails to import and mount datasets on boot. PVE however creates directories which will then prevent zfs from mounting the datasets afterwards. Also one of my pools needs manually importing now instead of automatic mounting like...
  5. [Tip] fast reboots with kexec

    Install the package: echo "kexec-tools kexec-tools/load_kexec boolean false" | debconf-set-selections apt-get -y install kexec-tools Create /etc/systemd/system/kexec-pve.service with content: [Unit] Description=boot into into the current pve kernel Documentation=man:kexec(8)...
  6. Discussion: Best practice for unprivileged containers

    First of all, thanks for this feature! I'm now converting almost of my containers into unprivileged ones. But as i'm doing some kind of Docker-like separation of code and data on almost all services using a lot of mountpoints, i just felt some need to discuss things ;) Example: I have some...
  7. hint: ZFS w/ lz4 vs. logrotate gzip

    Me being a curious guy which loves ZFS since years, i was installing ZFS on my Desktop to (slightly guided by this). I've stumbled upon an interesting statement: Ok, sounds legit. To apply to Proxmox and LXC Containers on ZFS, i've used this handy snippet ($TANK is the ZFS dataset which holds...
  8. hint: ZFS and updatedb.mlocate cron job

    The default updatedb.mlocate cronjob takes hours due to large amount of lxc zfs datasets. If you want to disable zfs for this scan, just add zfs to PRUNEFS in /etc/updatedb.conf.
  9. API: force flag

    Hi all (or in this case, Hi PVE devs *g*)! Right now i'm trying to debug a new ansible module which is able to handle KVM via API (leveraging proxmoxer). It works pretty good from the start, but i found a small glitch which i'm trying to debug (if we need to take care of in the module or in...
  10. Intel Skylake iGPU (i915) breaks Proxmox 4.1

    I've just deployed PVE 4.1 on a machine going to be a storage server (samba inside lxc). As theres not that much load, we decided to cut some money and just use an i3-6100. Installer went through without problems, but first boot hangs just 8ms after initrd's kernel kicks in. It took me a while...
  11. Apparmor: fills up log with denied ptrace messages

    My log now gets filled up with messages like this: Jan 08 08:17:54 itchy kernel: audit: type=1400 audit(1452237474.036:1468): apparmor="DENIED" operation="ptrace" profile="lxc-container-default" pid=19654 comm="ps" requested_mask="trace" denied_mask="trace" peer="unconfined" Jan 08 08:17:59...
  12. [script] Sequential ZFS scrub for cron

    As i don't want to start scrubbing all pools in parallel, here's a small script that does start scrubbing for pools sequentially, which can be added to cron, e.g. cron.monthly
  13. ZFS auto snapshots

    Just tested this (being used to this from BSD)...Might be worth to pack this into an upcoming pve release (or at least the wiki page) https://github.com/zfsonlinux/zfs-auto-snapshot wget https://github.com/zfsonlinux/zfs-auto-snapshot/archive/master.zip unzip master.zip cd...
