Hello, We expect the same, but only from older version to newer version. We installed a new node its up to date, and i can not migrate to this node from older nodes. New node: proxmox-ve: 5.2-2 (running kernel: 4.15.17-1-pve) pve-manager: 5.2-3 (running version: 5.2-3/785ba980)...

Hi, Please try to boot your server from a live CD (live ubuntu, systemrescuecd etc) and try to mount /.

I experience the same. Im using Openvswitch, i configured rate limit to 10, but nothing happened.

Is there a documentation how possible to reproducate it? We managing ~15 server (each in single mode) with local mdraid in RAID1, without any issue.

Please paste the image details. rbd info pool/image

No. I simply wrote, if you want to mount RBD image with extra feature sets, you can do this on this way. QEMU using libvirt for direct connection to RBD images, and LXC doenst have enabled these features by default, because its also using KRBD.

Hi, Use NBD for mapping. Its slovest than KRBD but working with all new moder featuers: modprobe nbd rbd-nbd -m mon1,mon2,mon3 --user CEPHUSER -k /etc/pve/priv/ceph/whatever.keyring map pool/image rbd-nbd unmap /dev/nbd0

Its called "fake raid": https://wiki.archlinux.org/index.php/Installing_with_Fake_RAID#What_is_.22fake_RAID.22 I prefer this way, yes, but as r.jochum mentioned, you can also use ZFS Raid1.

Hello, THis is not hardware raid, this is a software based raid solution, what require its own drivers. Dont use this, create softraid in Linux.

Hi, 18 days ago, loadavg code merged into LXC, as an opt-in features: https://github.com/lxc/lxcfs/pull/237 I would like to ask, when these feature will be available in LXC on Proxmox?

I guess you reach the limit of this gigatib link during migrate, right?

Hi, Do you have gigabit network?

You can install Proxmox itself without any issue, and you can use container based virtualisation. But for KVM, you ned nested virtualisation, what non existing in virtualbox

Hi, Is there a simple way to mount (ceph) snapshot as a read-only disk inside the VM?

LXC with Ceph, basically mount images with using krbd module, and container using the /dev/rbdX devices. IF you don't have anyway ceph cluster, there is no advantages on this setup.

Hi, In one system what we manage, we have Duo based 2fa. In this env, we implemented 2fa using with Duo Authentication Proxy, what basically connect to Active Directory, add duo based 2fa features, and providing LDAP, Radius, etc auth interface, what you can connect to your system. With this...

thanks, interesting! And bandwith is one thing, but more important, the max latency is half with rdma!

Hello, For this solution, you need nested virtualization. However, Virtualbox doesnt support this: https://forums.virtualbox.org/viewtopic.php?f=7&t=86922

Hello, https://access.redhat.com/sites/default/files/attachments/20150325_network_performance_tuning.pdf https://darksideclouds.wordpress.com/2016/10/10/tuning-10gb-nics-highway-to-hell/ http://fibrevillage.com/sysadmin/91-tcp-performance-tuning-10g-nic-with-high-rtt-in-linux

Hi, Yes, with openvswitch and proper sysctl configs (large tcp windows, etc, you can find many tutorials on internet), 9k mtu its working.
