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 at first and more
flow thereafter.
3) New CentOS7 installation on the same Network as Windows 2012, same
result no speed ... ! but vm windows OK !
|
--10.0.1.193-- VM Windows 2012 (OK)
Internet --- (200.13.XXX.XXX)--VR--(10.0.1.1)
| --10.0.1.42
-- VM CentOS7 (NOK)
Conclusion, it must come from taking into account the network under
Linux I suppose ... and that since the migration in version 4.13 ...
I don't understand !
If anyone ever had this problem ...
Thank you
Olivier

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.

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 <None>? in the XenCenter.
I have no traffic on my VMs, but on virtual routers yes.
Ex: From the router:
wgethttp://xxx.xxx.xxx.xxx/x86_64/CentOS-7-x86_64-Minimal-1908.iso
<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
Olivier
