Thanks. This solved my "problem" ;-) And remembered me that I need to study systemctl .... ;-) In my office, my personal main workstation is a Proxmox install that I also use for tests. Having 12 tty (in the past tried more, but ...), is very useful (IMHO). I can open ssh + tmux/screen...

More a Debian question that a specific Proxmox question ... I usually configure my personal box with 12 tty (tty1-ttyC --> ALT-F1 to ALT-F12). Until Proxmox 3.x I define them in /etc/inittab and /etc/securetty (if I remenber well). Proxmox4 uses Debian 8 and things are differents. Tried to...

If can be useful, I have tested it to the same config and with or without barrier=0. No real difference. disks settings (for 4.4): /dev/md2 on / type ext3 (rw,relatime,nobarrier,errors=remount-ro,data=ordered) /dev/mapper/pve-data on /var/lib/vz type ext3 (rw,relatime,nobarrier,data=ordered)...

Since Proxmox 1.x I had often "played" with the .conf file editing it as I need. I could clone a VM simply copying and modifying the .conf file I can move/copy disk images if needed. I understand that this can easily leads to mistakes, but it is really pratical for simple servers management...

Sorry for resuming this old post. Looking around on forum and google didn't give a solution. Tried "barrier = 0" and " --rootfs local:0", but still have Proxmox 4.4 much slower that 3.4 and with load average much higher (same simple hardware: SATA software RAID, 32 GB RAM). Did anyone find a...

Any hints? Some examples (two 4.4.n + one 3.3.m; same HW, similar VMs, activity) : 16:36:10 up 4 days, 22:29, 2 users, load average: 1.69, 1.42, 1.30 # pveversion -v proxmox-ve: 4.4-86 (running kernel: 4.4.49-1-pve) pve-manager: 4.4-13 (running version: 4.4-13/7ea56165)...

Problem still present for Centos 6.x (yum updates of initscripts package). P.

As in similar post before, there is this solution (install X on the host): https://pve.proxmox.com/wiki/Developer_Workstations_with_Proxmox_VE_and_X11 HTH. P.

Setting vm.swappiness = 0 in /etc/sysctl.conf + update Proxmox and reboot seems to solve my swap problems (the simple change of swappiness without reboot (and update), give no results). Anyway, I still have strange behavioural in all my 4.4 boxes: high load (compared with 3.4), and strange...

# pct list extract the ID and # pct enter VMID ;-) P.

I am migrating my olds Proxmox 3.4 to new 4.4 servers. Same hardware, same VMs, the node's cpu load is noticeable higher in 4.4 than in 3.4 (1.5-3.x in 4.4 Vs 0.3-1.1 in 3.4). And was worst before restoring the VMs as chroot (--rootfs local:0) If I try to monitor the cpu usage into an LXC...

As in 6.x, it seems that the host's kernel inserts messages in the syslog of the guest. I noticied it for the iptables messages from shorewall (that I use on the host). I only forward few ports (80, 443, 20,21), to the CT, but In the /var/log/messages of the CT I have some rows that reports the...

Tried swappiness to 0 into 2 server. Similar behavioural of swappiness to 1 Setted the value via sysctl vm.swappiness=0 without reboot the server. box1 pveversion report 4.3-12 kernel 4.4.24-1-pve box2 pveversion report 4.4-5 kernel 4.4.35-2-pve For both: The host phisycal memory is 32...

How did you "patch Proxmox VE"? Probably /usr/share/lxc/... is where to search, but if there is a way that doesn't require to understand and modify to much ... In the meantime I simply changed the string "5.11" with a "6.7" in the /etc/centos-release container and the new backup had been...

I know the EOL, but as we all know, there are legacy applications that need to continue works also if after EOL (usually in Intranet). If you know any warkaround to have it in a LXC container ... :-) Thanks, P.

trace which programs is using swap isn't a simple activity :-( Anyway, done some tests: Setting swappiness to 10 seems give no differences. Setting swappiness to 1 seems to slow down the swap consumption, but the trend seems similar. I have read different opinion to the option of setting...

I don't know exactly why, but the documentation say this and if I try to restore a 5.x vzdump I obtain: # pct restore 35259 vzdump-openvz-35259-2017_02_22-00_45_02.tar.gz --rootfs local:0 extracting archive '/tmp/vzdump-openvz-35259-2017_02_22-00_45_02.tar.gz' Total bytes read: 12593602560...

swappiness default is 60 both for 3.4 and 4.4. I But the different kernel seems use a very different swap policy. I tried to set swappiness to 10 into 3 different 4.4 servers (and cleared swap). In a couple of days we can see if there is any differenty result Best Regards, P

Ok. As I supposed. Nested Proxmox ;-) Good for small containers. Any tricks for running Centos 5.x on LXC? Thanks, P.
