The kernel panic I got was is a vm with VirtIO SCSI controller.
With lspci I see:
00:05.0 SCSI storage controller: LSI Logic / Symbios Logic 53c895a
In the Proxmox guide I read that with VirtIO SCSI Proxmox emulates by default a LSI 53C895A controller.
Could you please explain what you meaned...
Hi Tom, thank you for your answer.
Since Proxmox 4.4 I have been using the default controller virtIO SCSI which seems to be the recommended one (this is the first kernel panic I got in years). 90% of my vms are Debian based (mostly jessie and stretch).
Why do you advise to use the older...
Hi,
I also got a kernel panic (Proxmox 5.1) on a vm Debian 9.3 with PostgreSQL 10 (a OS disk and a data disk, both SCSI). I recently upgraded the vm kernel to Debian 4.9.65-3+deb9u2 (2018-01-04).
I am trying to understand what it's causing the problem.
From what I see it could be related to...
Latest tests:
openvpn with tcp and udp showed similar values (8-11MB/s). udp performed better but still close to tcp values
openvpn without encrpytion (--cypher none): 12.5 MB/s
In another datacenter with a openvpn server (tcp, encrypted) installed on a brand new physical server I got 24 MB/s...
I did some test with iperf3
It seems a problem with the VPN logical/software interface (maybe related to openvpn?)
On the public physical NIC (ethx) I get 65 MB/s, which is reasonable value. (In the private NIC I get 90 MB/s)
On the VPN logical NIC (VPN99) I get the same 10-12 MB/s
Could be...

Hi Everyone,
I am using a OpenVPN server (Zeroshell 3.8.2, Linux distribution) on a Proxmox VM environment (enterprise repo).
The problem is that the vm has really poor network performance on a full Gb network.
Best (unexpected) results are with Intel e1000 and vmxnet3 driver, but we are...
As advised, I developed a small virtual environment with a 3 node Proxmox cluster and a FreeNAS 9.3.
FreeNAS is configured as iSCSI target (40GB zvol) which is connected to the Proxmox cluster (not LUNs directly).
On the top of it there is LVM. The 40GB zvol is automatically “formatted” with...
Hi everyone,
I am currently using a 4 node Proxmox 3.4 cluster on a NFS storage, mainly used for web applications.
I would like to expand the cluster and above all use it on a SAN storage.
The problem is that I do not find a lot of info (manuals, books, forum, etc.) on how to develop a SAN...
Thank you very much for your replies. I just bought "Mastering Proxmox", Ceph could be a good solution, I am going to read about it.
I don't like local storage too, but with a RAID 1, spare and physical backup I don't think it's so bad..
Hi everyone,
I would like to virtualize a PostgreSQL database in production environment (KVM) and I would like to know if someone of you has been using it running on local disk (for example RAID 1 SAS, where Proxmox 3.3 is already installed) or NFS storage (or other storage solution..).
I read...
