How to set the public IP address of a KVM virtual machine?

Hi All,

I need a server (to start with) where I can do solution demos and build acceptance platform to perform upgrades etc.
For example, say a hosting company wants to design a solution where they want to move into ceph and openstack . and want a demo of how it looks like and how it works .. those are built virtually .. so this server will host a lot of virtual machines .. like 3x controllers, 3x ceph mons, 4x ceph osd, 4x hypervisors , 1x storage, 1x router , 3x object storage etc .. . you get the idea..

I already have a few servers from a provider, but the prices are getting higher, so I am just checking out what I can get. (maybe I am paying more)

Requirements:

at least 24 threads .. the more the better .. but not more than 40 threads ( can be amd or intel ) 1x ssd disk for the OS (can be 480gb min) and 2x 1 TB nvme .. ( i do not need raid , this has no customer data) 128 gb of ram Unmanaged kvm/idrac access preferred . but not a necessity. OS to be installed is ubuntu-focal minimum with only ssh enabled via ssh-key Bandwidth -- 99% incoming -- imagine 20-30 virtual-machines doing apt-get every week or doing git clone from github every few-days as a part of their build .. .. the only ports open = ssh and https ( say 1-2 hours per month, when a public demo is required) ... IPs - one for the main server, 3-4 additional Location: Europe preferred, but US is also OK.

Please do not ask me for a budget. But feel free to post your recommendations.


Thanks.

Hello,

So with the recent announcement of CentOS coming to and end i find myself wondering which is the best option for a new Dedicated server.

Do I still go with CentOS 7 or is there an alternative option now?

I know that CentOS is only EOL in 2024 and CentOS 8 is EOL now in this year 2021. So it makes very little sense to go with CentOS 8.

Any opinions welcome

Hello, i installed proxmox on server. Then i created Vm s on it. I have on ip which is for root also for the server.

Thanks

Hi there,

I'm currently struggling with creating a VPS on a Dedicated server.

I've purchased quite a high spec Dedicated server which is running Windows 2019 with Hyper-V installed and I'm looking at installing Ubuntu 16.04 and running it as a VPS off of the Dedicated server so I can allow my friends to make use of the server. I've purchased a failover IP address and I've attached it to the main Dedicated server but I'm a bit confused on how I am suppose to tell Hyper-V to use the additional IP only in that one VM box.

Please feel free to burn me for my stupidity but I could really do with some advice - thank you in advance.

Kind regards,

Hey guys, I have a dedicated server from hetzner that has VMware ESXi and many VM. I ordered an additional IP address but I don't know how to connect those IPs to the main IP address.

I know I can do it by defining a bridge in one of my machines, Is that correct? and if is true how can I do it?

I want to run 6 virtual machines at the same (windows 10 will be installed on all of them)

Each Silver 4124 has 12 cores (2.2GHz) so two equals 24 cores total. Each VM will be assigned 4 cores and 8 GB of ram.
Will the VM's run smooth? I want to run a game client on each VM.

For reference, I have a :
VM with 2 cores, 2.6GHz
VM with 2 cores, 2.7GHz
Both of these are able to get the job done running the game client.

Hi all,

I'm new here and this my first post

So I'd like to get my own dedicated server and set it up at home to be used for games only but I have no idea what kind of specs that is needed when it comes to servers and the distribution of system resources such as CPU, RAM etc. Storage is self explained obviously.
I'm looking to host like a Minecraft server, 7 days to die server, Rust server etc but in general, if possible to say, how many game servers can you run on a single machine?
What is a good server Intel Xeon CPU these days that is not overkilling my needs to run a few game servers on the machine? Is 64 GB of RAM enough to start with?
What is best for my needs when it comes to the server type like a tower or a rack?

I'm just trying to get an estimated cost to set this all up and i'm a bit overwhelmed what is enough and not so my apologies if I don't provide much information so if you need any more details in order to assist, let me know and I'd be happy to be more specific in the topic .
Internet speed is not an issue as I have 1 Gbit up and down.

Thanks in advance!

Hello,

I have servers with multiple NICs connected to different internet lines.

In the past on CentOS 6 and 7 I could easily setup the NICs by using the following commands for each NIC(I did not use NetworkManager)
ip route add 123.123.123.123/28 dev eno1 table 1
ip route add default via 123.123.123.123 table 1

ip rule add from 123.123.123.123/28 table 1 priority 100

(while using a different table number and priority for each NIC)

and to make the above manual commands persistent, convert to the corresponding files in
/etc/sysconfig/network-scripts/route-eno1
123.123.123.123/28 dev eno1 table 1
default via 123.123.123.123 table 1

/etc/sysconfig/network-scripts/rule-eno1
from 123.123.123.123/28 table 1 priority 100

However I am not really that familiar with network commands, and can't seem to figure out how to get it to work in CentOS/RHEL 8.
What are the corresponding commands in CentOS/RHEL 8 to make the above settings persistent?
The manual "ip route" and "ip rule" commands work fine.

Thank you.

Looking for 32 cores / 64 threads (or more), 256GB ECC RAM, two 2TB NVMe SSDs. I'll handle all server administration. Access via KVM over IP (or similar) would be great. Not looking for the cheapest. I'd rather pay for better support as there might be times where I need a little helping hand. I'll also need a block of IPv4 and IPv6 addresses and this will be hosting virtual machines.

if the ip of the visitor is ipv6, then $remote_addr is not showing the correct IP address.
the issue is similar to this
https://github.com/nginxinc/docker-nginx/issues/18

I want to have the correct ipv6 address. How can I do that?
