Hi all,
I meet a strange problem that my virtual router can access Internet and my
user_vm can access virtual router but my user_vm can't access Internet.Is
there anyone can provide with some suggestions?Thanks!

Which version of cloudstack are you using ?
Is it isolated network ?
Did you add egress rules on your network to allow outgoing guest traffic ?
Thanks,
Jayapal

Hi Jayapal,
Thank you for your prompt reply,your advice is very useful to me.The
network strategy in Cloudstack4.2 is a bit different from cloudstack4.0's
and I have add firewall rule to Egress rules in my isolated guest
network.My vm can access Internet now.

Hi Jayapal,
By the way,I think cloudstack4.2 CPVM does support lXC very well.How do you
like?

Hi. i try create the shared network with cloudmonkey with command:
create network name=Shared-Network displaytext=Shared-Network
networkofferingid=f03374d2-a8dc-40ab-8839-94dc31238410
physicalnetworkid=246635bf-1cda-4e1b-bc8f-b4ddb242e81c gateway=10.1.1.1
netmask=225.225.225.0 networkdomain=***
Not currently in front of my computer to check but I suspect that as its a
Shared Network you are trying to create you need to specify the domain unless
you are trying to share at Zone Level.
You are also specifying an IP Range but no VLAN ID, theses settings are always
required together.

Thanks for reply. I found solution after detailed reading cloudstack logs.
In the information flow hard to see right info.
So who will read this , look at cloudstack-menagement.log
Now i have problem with VM creation, but this is another story
Hello
Cloudstack 4.13, Xen 6.5
I would like to know if there is a command to 'clean up' in the
Networking tab unused networks in XenCenter !
Can I delete networks with a Link Status ? in the XenCenter.
I have no traffic on my VMs, but on virtual routers yes.
Ex: From the router:
wget http://x
Dear All,
I have changed the interfaces file on ubuntu and getting the following

Hello Olivier,
You can check QoS setting on the VIF on the VR which is connected to the
network which also connects to your VM. As far as my knowledge is concerned,
XenServer Applied QoS for outgoing traffic only not for Incoming traffic, So it
might be possible that traffic sending out to t

Hello Vivek,
Thank you for your answer.
There is Qos on the VR and VM interfaces but I don't know who manages
it, Cloudstack, XenCenter or Xen Server?
Other operation that I made:
1) New installation Windows 2012, everything is OK good speed
2) New CentOS 7 installation Very poor flow ... fast
Hello,

Hi Olivier,
Upgrade to 4.13 should not be a problem here. I would suggest:
- checking traffic shaping on XenServer side - to confirm what is/is not in
place (we don't know your network offerings/compute offerings network rates
and such)
- Confirm VM/drivers used inside VMs are all up to date (6.5
Hi Andrija,
Thank for your anwser ...
1) My Cloudstack is 4.13
2) Can I mix a version of xen 6.5 and xen 7 in the same cluster? (I
think I cannot move a VM from one cluster to another)
3) 200.13.xxx.xxx est un de mes serveurs sur mon réseau physique
I think the problem comes from my service
(mon français n'est pas si bon) - but if that is a physical server - than
it's a valid test - beside the traffic will go through the VR (from VM via
VR to that external host) - here you have NAT over relatively slow VR
(CPU/RAM) and over the throttled interface most probably.
In general, you shoul
Hi Andrija,
You wrote that there would be my CPU / RAM ratio which would cause the
throttled on my interface.
What would be the right CPU / RAM ratio?
If you have a recommendation.
I think my problem comes from there ..
I made a VM with 4GB RAM and 4 vCPU at 2Ghz and it works very well!

Not necessarily - i.e. you should still observe multiple hundredns of
megabits/sec with default VR offering, with the routing process.
I would pay attention to the network throttling set on XS side, as Vivek
has already suggested in another email.
