Routers on specific cluster

[Vivek Kumar]

Hello Guys, 

So I am using ACS 4.13 with Advance zone. I have 5 KVM cluster and 5 VMware 
Cluster. So whenever I provision any VPC for any of the cluster, VPC VR always 
go and sit on KVM hosts, we have around 200 VPC VR and all are there in KVM 
zone.  Well for functionality prospective I don’t have any issues but is there 
any way to provision router in specific cluster as well. 


Storage tag and host tag doesn’t work in case of VR’s offering. 


Regards
Vivek Kumar

Hello Andrija.

Gluster as primary storage works fine. Storage migration, with powered 
off VM's, it's working  too. My problem is just doing this with VM's 
running.


I'm using Ubuntu 20.02, CentOS 7 and Windows 10 and 2016 for testing and 
not working.


But it is the life, thaks all

Best regards,

If you are using Ubuntu - all fine - qemu-kvm supports live storage 
migrations from Ubuntu 14.04 at least, an onwards.
If you are using CentOS 7, you have to use qemu-kvm-ev from the oVirt 
repo ONLY - all other versions of qemu-kvm do NOT support storage live 
migration (Redhat revoked it for $$$ reasons, while it was working 
fine in CentOS6)


If your tested it and it worked from Gluster to NFS - that's (great) 
news (for me).


Hope that helps,

That is indeed not supported with KVM and also not on the roadmap
at the
moment.

Re: Virtual Router Domain Name Handling

[Serge Byishimo]

Hi Andrija,

The reverse proxy also was my first instinct, I already did it and it was
successful, I used Nginx as a reverse proxy inside the VR and redirected
the traffic to instances. I was hesitant too but I have to keep that in
mind that they might get destroyed and I would have to reconfigure the
proxy. Thanks.

Regarding multiple emails, Sorry it is my frustration, sometimes I just
remember a detail that I should have shared and then I end up sending
another email, I’m going to avoid that in the future.

Thank you so much you have been a helpful and wonderful community.

Best Regards,

Re: Virtual Router Domain Name Handling

[Andrija Panic]

Based on your exact drawing (assumes a single public IP, and a single VR IP
that receives all traffic on ports 80 and 443) - this can NOT be achieved
by ACS itself.

You need a reverse proxy inside VR - and you are risking having a mess -
but I'm not saying you can't do it.
All ACS port forwarding rules are in iptables (iptables-save | less) or
loadbalancer implemented via HAPROXY can pass all traffic to a dedicated
internal reverse proxy VM - so you forward 80/443  from home public IP -->
VR port forwarding --> to an internal single VM (that has nginx/varnish
installed)
If you opt to modify VR itself, that would be a problem to manage in the
long run - as soon as you restart network with "clean up" - the existing VR
is destroyed and a brand new one is created for that network (or for VPC,
if you are working with VPCs)
So you would need to automate such thing in some way.

Hope that helps,

Re: Documentation of available guest VM / instance settings

[Andrija Panic]

You can send a custom XML chunk (via API only), to be incorporated as part
of the VMs XML definition - so that should allow you to add sound card, or
some pass through any HW device to the VM (or enable huge pages, etc)

I forgot the name of the feature (very tired atm), perhaps @Nicolas Vazquez
ShapeBlue  can refresh pls?

Where did you read this? Live Migration with the KVM hypervisor works 
just fine.


Wido

Yet on the manual citation, it said that migration just can occur 
from CEPH/NFS to "SolidFire Managed Storage". On my tests we are

Virtual Router Domain Name Handling

[Serge Byishimo]

Centos8
Cloudstack 4.15
Hypervisor KVM

This is a drawing of what I’m trying to do

https://ibb.co/pKvzhHj

I have different domain names that I want assigned to instances IP ports

In the DNS, I put one public IP address that I have from ISP 209.150.X.X,

The cloudstack Virtual Router is at 192.168.1.86

Then in my home router I forward traffic from 209.150.X.X port 80 and 443
to the cloudstack virtual router at 192.168.1.86 also port 80 and 443

from 209.150.X.X :80 to 192.168.1.86 :80
from 209.150.X.X :443 to 192.168.1.86 :443

How do I engage the virtual router to forward that traffic at respective
instances IP Ports?

ACS Virtual Router Details:
https://ibb.co/1Jr2DZT


In other words, I need to know how to do port forwarding in the virtual
router

I have Basic Network with Security Groups, I use Ingress Rules to allow
incoming traffic in the Instances

For example:

example.com to instance IP : 192.168.1.85:8080
another.com to instance IP  : 192.168.1.91:8443

I can ssh inside the Virtual Router VM, I just need to know what I should
do!

I was thinking on installing NGINX as a proxy on the ACS virtual router VM
to forward the traffic it is receiving to Instances, but i’m not sure if
that will work.

Thank you!

Another thing to keep in mind - if you work from office - usually there can

i.e. you and your colleague can not connect at the same time to the same

I am trying to setup Remote Access VPN on an DefaultIsolatedSourceNAT

network


I have created the VPN and a VPN user and pasted the shared key into a

Windows client but I am getting an error stating


the L2TP connection attempt failed because the security layer encountered

a processing error


I have looked through the documentation and have set


Requires encryption

MS-CHAP v2

PPP -> Enable LCP extensions


I haven't however changed the CloudStack parameter


remote.access.vpn.client.iprange setting from it's default, does this

need to be altered to match guest isolated network CIDR's? Not sure how the

virtual router sets up the VPN


Or am I doing something else wrong?


Thanks


Brian

Re: Best practice moving cloudstack 4.13.0.1 management server from centos 6.10 to Ubuntu 18.04 LTS

[Rohit Yadav]

Hi David,

The static-roles based commands.properties is deprecated now, while we still 
support it we don't ship a default settings/file with CloudStack now. Instead 
we've moved to dynamic roles, please see 
http://docs.cloudstack.apache.org/en/4.13.1.0/adminguide/accounts.html#using-dynamic-roles


Regards.

Hi

Sorry for late reply.
I figured out the reason why I couldn't log in to the GUI on the new ubuntu 
server.
Seems like I need to copy the old commands.properties file from the old centos 
6.10 server to the new ubuntu server... (?)
I thought cloudstack 4.15 didn't use it anymore, especially since it is not 
included in the 4.13-4.15 installation?

Does anyone know which setting(s) in the commands.properties file I need to 
look into?

Re: Prediction or studies for KVM live migration.

[Kalil de Albuquerque Carvalho]

Hello Wido.

Sorry about that. I was not so clear, or made some misunderstanding.

Doing some corrections, I've tested migration from Gluster to NFS, and 
the reverse, and every think worked well. So, please, disregard this 
part of my question. I should would did this test before made the question.


My question, now, is when will be support, if will be, with the running 
VM's. Today, I'm testing the version 4.15, just working with power off VM's.


Best regards.

Yet on the manual citation, it said that migration just can occur

Re: Virtual Router Domain Name Handling

This is a drawing of what I’m trying to do

I was thinking on installing NGINX as a proxy on the ACS virtual router VM
to forward the traffic it is receiving to Instances, but i’m not sure if
that will work.

Virtual Router Domain Name Handling

[Serge Byishimo]

Centos8
Cloudstack: 4.15
Hypervisor: KVM

I have different domain names that I want to be assigned to instances IP
ports

In the DNS, I put one public IP address that I have from the ISP 209.X.X.X,

The cloudstack Virtual Router is at 192.168.1.86

Then in my home router, I forward traffic from 209.X.X.X port 80 and 443 to
the cloudstack virtual router at 192.168.1.86 also port 80 and 443

from 209.X.X.X :80 to 192.168.1.86 :80
from 209.X.X.X :443 to 192.168.1.86 :443

How do I engage the virtual router to forward that traffic at respective
instances IP Ports?

In other words, I need to know how to do port forwarding in the virtual
router

I have Basic Network with Security Groups, I use Ingress Rules to allow
incoming traffic in the Instances

For example:

example.com to instance IP : 192.168.1.85:8080
another.com to instance IP  : 192.168.1.91:8443

I can ssh inside the Virtual Router VM, I just need to know what I should
do!

Thank you!

Hi

Sorry for late reply. 
I figured out the reason why I couldn't log in to the GUI on the new ubuntu 
server.
Seems like I need to copy the old commands.properties file from the old centos 
6.10 server to the new ubuntu server... (?)
I thought cloudstack 4.15 didn't use it anymore, especially since it is not 
included in the 4.13-4.15 installation?

Does anyone know which setting(s) in the commands.properties file I need to 
look into?
