Accessing Virtual Instances from other systems on the same subnet
Hi Guys,
I have setup cloudstack management and hpyervisor (KVM) on machine 1 and machine 2 respectively. I am successfully able to ping the instances from hypervisor machine (machine 2) but I can't ping it from any of the other machines on the same subnet. Why is that? How can I make it work?
Another observation is that I can ping secondary storage and primary storage vm's from any system on the same subnet without any extra configuration. Can I have similar configuration-free setup from virtual instances? If not, what else I have to do to ping/access virtual instances from other machines in the same subnet.
Regards
Adeel

Yes, they are using the same switch

Bingo! When I turn off the firewall of the "host" carrying the VM, I can ping and ssh into the VM. It means I will have to add some rules to the iptables but I don't know exactly what those rules would look like. Can you please help me

One more thing. The default template just downloaded. But the same result. I can ping my instance VM's from the "host" they are running on but not from any other machine. I will repeat the steps you told and will get back to you.

Well, if that is the case, I would do the following while pinging from the
outside world:
- tcpdump inside these problematic VMs to check if they can see ping
packets;
- If they cannot, I would check iptables rules (iptables -L) on both VMs
and hosts;
- Then, I would check the tcpdump also on a host where the VMs are
running to see if the packets are at least getting into the host.
- I would also check the arp table of your client PC (just in case)

If you are using basic zone then you have to add rules to your security
groups to allow traffic between VMs. Everything is denied by default.

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Rafael Weingärtner <ra...@gmail.com>.
Unless I am mistaken, ACS should be configuring these things.
I have never played much with KVM, so maybe some other guys can jump in as
well.
Do you have a user in ACS slack channel? You may find more prompt answers
there

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Muhammad Adeel Zahid <16...@lums.edu.pk>.
Bingo! When I turn off the firewall of the "host" carrying the VM, I can ping and ssh into the VM. It means I will have to add some rules to the iptables but I don't know exactly what those rules would look like. Can you please help me

One more thing. The default template just downloaded. But the same result. I can ping my instance VM's from the "host" they are running on but not from any other machine. I will repeat the steps you told and will get back to you.

Well, if that is the case, I would do the following while pinging from the
outside world:
- tcpdump inside these problematic VMs to check if they can see ping
packets;
- If they cannot, I would check iptables rules (iptables -L) on both VMs
and hosts;
- Then, I would check the tcpdump also on a host where the VMs are
running to see if the packets are at least getting into the host.
- I would also check the arp table of your client PC (just in case)

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Rafael Weingärtner <ra...@gmail.com>.
I also have one more thing, how is the is the network setting?
You said that the VMs and other physical PCs are in the same network (
10.0.0.0/24). How are these devices connected? Are they using the same
switch?

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Muhammad Adeel Zahid <16...@lums.edu.pk>.
One more thing. The default template just downloaded. But the same result. I can ping my instance VM's from the "host" they are running on but not from any other machine. I will repeat the steps you told and will get back to you.

Well, if that is the case, I would do the following while pinging from the
outside world:
- tcpdump inside these problematic VMs to check if they can see ping
packets;
- If they cannot, I would check iptables rules (iptables -L) on both VMs
and hosts;
- Then, I would check the tcpdump also on a host where the VMs are
running to see if the packets are at least getting into the host.
- I would also check the arp table of your client PC (just in case)

I also tried adding the Instance VM's using default template but that template is stuck in downloading. I have downloaded 2 other ISO's meanwhile but default template's download is still in progress.

Yes, I added the basic zone. I have one server running the management studio and KVM both and another machine running kvm alone.

Hmm, it should not be a problem just because you are using a ISO based VM.
Have you tried to instantiate the VM using the CentOS template that comes
with ACS?
These KVM servers you are using, are they real servers or VMs?
If you followed (
http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/qig.html),
Quick Installation Guide for CentOS 6 — Apache CloudStack ...<http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/qig.html>
docs.cloudstack.apache.org
High level overview of the process¶ This runbook will focus on building a CloudStack cloud using KVM on CentOS 6.8 with NFS storage on a flat layer-2 network ...
then you have deployed a basic zone.

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Muhammad Adeel Zahid <16...@lums.edu.pk>.
Hi Rafael,
Thanks for reaching out. I am not sure about traffic labeling and rest of the stuff. I have just setup the basic installation using this tutorial http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/qig.html and haven't explicitly set anything that is not in the tutorial. About the IP addresses of VM's. Yes, they seem to have a single IP (ifconfig). Please note that I am creating VM's from cenots 6.8 minimal ISO image that I intend to use later as template. Does that create the problem?
Adeel

Subject: Re: Accessing Virtual Instances from other systems on the same subnet
I asked a clarification because anything is a VM/instance (system and
users), I wanted to know if the VMs without access were either a system VM
(VR, SSVM, CVM or others) or a user VM.
Well, what is your setup? Are you using basic network where the public IP
is assigned directly to users VMs?
I asked you about the traffic label you are using for the public network.
System VMs get IPs on management and public networks. The SSVM has also an
IP on storage network. So, it seems that everything is fine with your
public networks, not so sure about the rest.VMs get an IP on Guest network.
The basic zone setup you will set the Guest IP as the public network (with
external access). Do these VMs have only a single IP?

Re: Accessing Virtual Instances from other systems on the same subnet
Posted by Muhammad Adeel Zahid <16...@lums.edu.pk>.
Specifically, by instances I mean the following
[cid:e42b05b3-32a0-4bdd-aeb5-8400b2c3c8ea]
I think, you people call it instance VM's or just VM's. You can see that my instance VM's has addressed 10.0.0.124 & 10.0.0.141 respectively. I can access or ping them from the host they are running on but I cannot access or ping them from any other machine on the same network i.e 10.0.0.0/24.
On the other hand there are system VMs like Primary storage and secondary storage VM's as shown in figure below.
[cid:112a895d-d500-4b43-8b0f-521b4e47bd9f]
I can access or ping these VM's using their public IP address from any of the systems on the same subnet (be they part of cloudstack installation or not). Now my question is, how I can access/ping my instance VM's from any system in the same subnet i.e 10.0.0.0/24?
Hope that clarifies the question

What do you mean by instances? User VMs?
I am assuming you are talking about the public IP. Did you set the name of
the public bridge properly (interface where the public traffic goes)?
