Virtual 7750 SR Available in 12.0.R4

[+gutsy81]

Hello Rifster.

I need your assistance and clarifications as regards the following portion of your post:


Go to /etc/libvirt/qemu/networks/ and create additional bridge xml files (link12.xml, link13.xml, etc.)

rifster@xubuntu:/etc/libvirt/qemu/networks$ ls -l
drwxrwxrwx 2 root root 4096 oct 11 00:16 autostart
-rwxrwxrwx 1 root root 228 sep 29 22:33 default.xml
-rwxrwxrwx 1 root root 405 oct 10 22:24 link12.xml
-rw------- 1 root root 405 oct 11 00:15 link13.xml
-rwxrwxrwx 1 root root 88 oct 11 00:11 link13.xml~
-rw------- 1 root root 405 oct 11 00:15 link24.xml
-rwxrwxrwx 1 root root 405 oct 11 00:10 link24.xml~
-rw------- 1 root root 405 oct 11 00:15 link34.xml
-rwxrwxrwx 1 root root 88 oct 11 00:12 link34.xml~

4.2 Type basic configuration and save:
<network>
<name>link12</name>
<bridge name='link12' stp='on' delay='0'/>
</network>


*****Kindly help with thw syntax/command to use in achieving the following:
Go to /etc/libvirt/qemu/networks/ and create additional bridge xml files (link12.xml, link13.xml, etc.)

******In the same vein, how do I edit the following; i mean the command to use
4.2 Type basic configuration and save:
<network>
<name>link12</name>
<bridge name='link12' stp='on' delay='0'/>
</network>


Your response would be highly appreciated.

You can try running SR VMs on recently released GNS3 1.1 (v1.0 is good as well). I got it working on Windows and Xubuntu. You can use the .qcow2 image, just import it as Qemu VM and assign 6 e1000 NICs to it (remember that 1st NIC is for CPM A/1). Only 1 copy of .qcow2 is needed, you can drag'n'drop as many SRs as you want (depending on your RAM of course). SR configs are also saved when you save your project. GNS3 guys did a hell of a job with the new software!

How did u import it as Qemu VM, would you mind to tell the steps? I am trying to figure it out but I did not see option for it.

Thanks.

Edit -> Preferences -> QEMU -> QEMU VMs
New -> type Name, leave as Default -> Qemu binary leave as is, assign 2000MB if RAM -> Browse for .qcow2 file for the Disk Image (hda) -> Finish

Then highlight it on the list and click Edit, on the Network tab increase Adapters to 6, leave Type as e1000.
If you right click on the list entry you can change the symbol, when you do it you can pick the Category in which it will be visible in the main topology window. I've got mine under Routers. Then just drag and drop it to your topology.

I noticed today that when you build the topology in GNS3 it's not possible to capture packets on the links between SRs. You can do it if you not use GNS and run it the "hard" way.

Hi Stephen,
No problem. Please see below.

*****Kindly help with thw syntax/command to use in achieving the following:
Go to /etc/libvirt/qemu/networks/ and create additional bridge xml files (link12.xml, link13.xml, etc.)

1. move to /etc/libvirt/qemu/networks/ folder
rifster@xubuntu:~$ cd /etc/libvirt/qemu/networks/

2. as root (indicated by sudo) open a txt editor (i'm using nano here) and edit a file (link12.xml)
rifster@xubuntu:/etc/libvirt/qemu/networks$ sudo nano link12.xml

******In the same vein, how do I edit the following; i mean the command to use
4.2 Type basic configuration and save:
<network>
<name>link12</name>
<bridge name='link12' stp='on' delay='0'/>
</network>

3. copy the config and paste it into the editor (to paste SHIFT + insert)
4. then to save the file press CTRL + X, press Y, and tap ENTER for the file name
5. when you type ls -l you should see something similar

rifster@xubuntu:/etc/libvirt/qemu/networks$ ls -l
total 16
drwxr-xr-x 2 root root 4096 paź 10 18:43 autostart
-rw-r--r-- 1 root root 228 wrz 29 22:33 default.xml
-rw-r--r-- 1 root root 5 paź 26 16:20 link12.xml

6. im not sure if it is required but i always change file rights and the owner

rifster@xubuntu:/etc/libvirt/qemu/networks$ sudo chmod 777 link12.xml
rifster@xubuntu:/etc/libvirt/qemu/networks$ sudo chown rifster link12.xml

rifster@xubuntu:/etc/libvirt/qemu/networks$ ls -l
total 16
drwxr-xr-x 2 root root 4096 paź 10 18:43 autostart
-rw-r--r-- 1 root root 228 wrz 29 22:33 default.xml
-rwxrwxrwx 1 rifster root 86 paź 26 16:20 link12.xml

Thanks Rifster.

You mean sudo nano link12.xml is feasible if link12.xml has not been defined or does not exist before, as you stated below?
2. as root (indicated by sudo) open a txt editor (i'm using nano here) and edit a file (link12.xml)
rifster@xubuntu:/etc/libvirt/qemu/networks$ sudo nano link12.xml

Thanks for making the steps so straight-forward.

Do have a nice week.

NICE!

I am currently trying to get this to work on Windows in GNS3.
It seems like the vSR is booting OK, but I cannot console to it.
All i get is connection refused to 127.0.0.1 port 5001.

How did you manage to console to your vSR's?

EDIT: I installed QEMU manually (http://qemu.weilnetz.de/w64/ - qemu-w64-setup-20140801.exe ), pointed my QEMU vSR binary to c:\programfiles\qemu\qemu-system-x86-64w.exe, and now I have console

[Stoffen]

GNS3 - QEMU

Under Edit -> Preferences -> QEMU -> QEMU VMs -> Edit your VM
Advanced settings, Additional Settings, Options: "-smp 2"

This will enable multi core system for the vSR.

During boot with this option enabled:
Enabled core count: 2

Where no option:
Enabled core count: 1

Still have some struggles with networking, but working on it

I faced this issue once, when after having 4 SRs working stable I started extra 2 and they didn't let me in via console. Probably it was in some way related to low memory as I was reaching almost ~7,5GB out of 8 on Win7. Before I installed GNS3 v1.1 I uninstalled previous one to have clean go. The only issue right now is the constant reboot. I must say it's a pain...

GNS3 - QEMU

Under Edit -> Preferences -> QEMU -> QEMU VMs -> Edit your VM
Advanced settings, Additional Settings, Options: "-smp 2"

This will enable multi core system for the vSR.

Great tip, thanks!

Still have some struggles with networking, but working on it

Yesterday I experimented a bit with new GNS and managed to connect Juniper olive, Cisco IOS (on dynamips) and ALU vSR, all in star topology connected together by Cisco IOU switch. If you have powerful PC you can do basically any multi-vendor topology you want right now.

For IOU setup I recommend following link:
http://www.routereflector.com/2014/04/i ... y-release/

To get IOU speaking to the rest you also need to change the gns3server IP binding from 127.0.0.1. I picked my LAN IP.
