Re: Network problem Cloudstack 4.13 Xen 6.5 Linux VM [URGENT] Mix Xen 7

[Andrija Panic]

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.

Re: Network problem Cloudstack 4.13 Xen 6.5 Linux VM [URGENT] Mix Xen 7

[Olivier GUIN]

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! 
(Linux/Windows)


Cheers,
Olivier

You are doing:   iperf3 -c 200.13.XXX.XXX -p5001

Why are you connecting to the IP of the VR? What kind of testing is this
supposed to be/show what?



Why not starting iperf server on Centos 7 and connect to it from Windows
2012 (and the other way around)?
This traffic is NOT going over the virtual router, but just via the same
"network" on XS.

I'll try ok


Alternatively, you can deploy VPC (multiple isolated networks behind a VR)
- and have VM1 in network1, VM2 in network2 - and do iperf between them
(traffic router via VR) - here keep in mind even if your VM's NIC are
1Gbps, but your VR NICs are 100 Mbps, you will be limited to the slowest
nic in the whole path/chain - 100 Mbps.

OK

Re: Network problem Cloudstack 4.13 Xen 6.5

[Riepl, Gregor (SWISS TXT)]

Hi Olivier,

It may also be a good idea to check your network offerings, perhaps there is an 
incorrect limit somewhere that wasn't applied previously and is now limiting 
the bandwith.
I remember having such an issue after an upgrade once.

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 the VM has some QoS limit. You 
can check that.

Re: Network problem Cloudstack 4.13 Xen 6.5 Linux VM [URGENT] Mix Xen 7

[Andrija Panic]

(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 should not keep mixed XS versions (whatever is true for
XenServer alone, irrelevant of the CloudStack), as 7.x is a big difference
to 6.5 and i.e. VM live migrations will not work (and I'm sure many other

Re: Network problem Cloudstack 4.13 Xen 6.5 Linux VM [URGENT] Mix Xen 7

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 offerings

I keep looking ...

But I think upgrading my Xen servers from 6.5 to 7 is a good idea.

Point 2 is important !

You are doing:   iperf3 -c 200.13.XXX.XXX -p5001

Why are you connecting to the IP of the VR? What kind of testing is 
this supposed to be/show what?




Why not starting iperf server on Centos 7 and connect to it from 
Windows 2012 (and the other way around)?
This traffic is NOT going over the virtual router, but just via the 
same "network" on XS.

I'll try ok


Alternatively, you can deploy VPC (multiple isolated networks behind a 
VR) - and have VM1 in network1, VM2 in network2 - and do iperf between 
them (traffic router via VR) - here keep in mind even if your VM's NIC 
are 1Gbps, but your VR NICs are 100 Mbps, you will be limited to the 
slowest nic in the whole path/chain - 100 Mbps.

OK

Re: Network problem Cloudstack 4.13 Xen 6.5 Linux VM [URGENT]

[Andrija Panic]

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 is an ancient
thing, not supported any more in ACS 4.14 that will be out soon)

You are doing:   iperf3 -c 200.13.XXX.XXX -p5001

Why are you connecting to the IP of the VR? What kind of testing is this
supposed to be/show what?

Why not starting iperf server on Centos 7 and connect to it from Windows
2012 (and the other way around)?
This traffic is NOT going over the virtual router, but just via the same
"network" on XS.

Alternatively, you can deploy VPC (multiple isolated networks behind a VR)
- and have VM1 in network1, VM2 in network2 - and do iperf between them
(traffic router via VR) - here keep in mind even if your VM's NIC are
1Gbps, but your VR NICs are 100 Mbps, you will be limited to the slowest
nic in the whole path/chain - 100 Mbps.

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 the VM has some QoS limit. You 
can check that.

I have no traffic on my VMs, but on virtual routers yes.
Ex: From the router:

 From the vm: 15 kbps!
Do you have an idea, I think it's since the migration from 4.11 to 4.13!

I have no traffic on my VMs, but on virtual routers yes.
Ex: From the router:

 From the vm: 15 kbps!
Do you have an idea, I think it's since the migration from 4.11 to 4.13!
Thank you

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 the VM has some QoS limit. You 
can check that.

Network problem Cloudstack 4.13 Xen 6.5

[Olivier Guin]

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://xxx.xxx.xxx.xxx/x86_64/CentOS-7-x86_64-Minimal-1908.iso -> 
200 Mbps

From the vm: 15 kbps!
Do you have an idea, I think it's since the migration from 4.11 to 4.13!
Thank you

Network problem cant start eth0 and eth1

[sandeep khandekar]

Dear All,
I have changed the interfaces file on ubuntu and getting  the following
error
How to solve it any idea
I cant connect to my management server now?

2014-03-19 18:40:01,067 INFO  [cloud.cluster.ClusterManagerImpl]
(Timer-1:null) Cluster node IP : 192.168.1.104
2014-03-19 18:40:01,072 ERROR [utils.component.ComponentContext]
(Timer-1:null) Unhandled exception
javax.naming.ConfigurationException: cluster node IP should be valid local
address where the server is running, please check your configuration

When I tried to check the status of management server I am getting the
following information

root@CLOUDSTACK:/home/cloudstack# service cloudstack-management status
 * CloudStack-specific Tomcat servlet engine is not running.

Now I cant configure eth0, eth1 interfaces also with DHCP I am getting eth2
interface up and running. If I delete
/etc/udev/rules.d/70-persistent-net.rules file will it solve my problem.

Thanks

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.

Re: Network problem

[Jayapal Reddy Uradi]

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,

For 403: Try what Geoff suggests.
For 401: Check if you're using port 8080, that requires apiKey and
secretKey to be set or you've authorization to execute this API (check user
type and ACL permissions).

Cheers.

Re: Cloudmonkey create network problem

[Geoff Higginbottom]

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.

Check and confirm the offering you are referencing is for a shared network, and 
has the Specify VLAN flag set, as this also enables (enforces) the allocation 
of a guest IP range rather than just the CIDR.

Also what account are you running this under, shared networks can only be 
created by Root Admins.
