Doesn't work anymore.. strange!

So my two examples are equivalents? 1 socket, 4 cores, undef vCpu == 1 socket, 16 cores, 4 vCPUs

Hello, I'm experimenting CPU and RAM hot plugging with KVM. I can add or remove RAM from a running VM. It works great! I have read that reducing RAM is not supposed to work, but all worked at the first try. Maybe I read outdated articles? (tested with proxmox 4.3, ubuntu 16.04 guest) I can...

Don't know what was wrong, I see it today... probably PEBKAC :D

Hello, Probably a dumb question... but I'm sure I was able to see the space used/left on my local LVM-thin storage on Proxmox 4.2 I don't see it anymore on 4.3. Is it me or it's missing?

I switched to KVM. LXC is not fully ready to use in Proxmox I think, especially with ext4 filesystem. I wanted to use LXC container because of performances but in fact performances are currently better with KVM.

Hello, Still evaluating Proxmox. I now have two test boxes in a cluster. Tried to move a running VM to the other node (online migration) and seem like this is not supported? I was sure this is something supported. Online migration only work with shared storage?

Thanks for the answer! Then, ZFS is not suitable for us. I have no problem using ext4/LVM, but as you can see in this forum, there is a lot of reports of slow IO performance (because of barrier=1 I think). A job that take 8min19sec with LXC/ZFS take 22min25sec with LXC/ext4. I wouild...

Hello, I just reinstalled my testing PVE box with ZFS instead of ext4/LVM because of (very) low LXC IO performance. My test box have a single SATA HDD and a small SSD for caching (not setuped yet). This seem a lot better now, but I have some questions coming from a ZFS noob. When I installed...

Didn't used ZFS. I have read that ZFS require a lot of RAM and preferred to keep the RAM for my containers. I'm still evaluating proxmox (I use if for years for my personal server, but first time I use it at work and first time with 4.x/LXC), so if my thinking is wrong, it's not too late to use...

I'm using LVM-Thin with raw image for my LXC containers. Currently testing proxmox on a desktop PC with a single SATA drive, but the prod will be on SAS or SSD drives in RAID10 on a hw raid controller with battery. So, I understand this would be safe to use barrier=0. It's easy to change that...

Hello, I have the same problem when I shutdown/stop then I start a container where I mounted a cifs share. The others containers continues to work, but the pct command hangs (even for a pct list). The web UI work but actions on containers just hang too. After 150-300 secondes (delay is not...

Thanks, it's working!

Hello, I'm trying to allow cifs mount inside one container. So I created a new file at /etc/apparmor.d/lxc/lxc-default-cifs with this contain: # Do not load this file. Rather, load /etc/apparmor.d/lxc-containers, which # will source all profiles under /etc/apparmor.d/lxc profile...

Oh, I did an apt upgrade of my test box and this updated lxcfs to 2.0.2. A reboot later, the issue disappeared.

Hello, The bug report I linked is against lxcfs pacakge, not lxc. Seem like the current version used by proxmox is 2.0.0.beta1. Is there a way to upgrade to a newer version? Also, I have this problem only with a ubuntu 16.04 template. The problem doesn't occurs with a ubuntu 12.04 template.

Hello, I installed a ubuntu 16.04 container in a fresly installed Proxmox VE 4.2. When I try to get memory stat inside my container with the "free" command, it reports a negative used memory: # free total used free shared buff/cache available Mem...

Thanks fabian. This is my first Proxmox server with ssd drive. How work ssd-cache? Does it require ZFS (currently using ext4).

Hello, I have some difficulties to understand how the "LVM-Thin" thing work. Seem like the old /var/lib/vz doesn't hold container data anymore. They are stored in a "thin lvm volume". Right? /var/lib/vz is now just a directory created on pve-root volume and this is where we stock vzdump, iso...

Hello, I have 2 proxmox nodes in 2 differents datacenters. Does it make sense to use the clustering functionality ? Thanks.
