What is working
Here is a list of what has been tested and works. You can extend this list by posting comments on what is working or not for you and I’ll update the list:
| OSPF (fxp0) | OK |
| OSPF (em0) | OK |
A few words about the patch
By default using JunOS with a non-patched Qemu, multicast based protocols didn’t worked. As I have very little driver coding experience (and time to learn), I patched Qemu to allow multicast frames to be received by JunOS, instead of being filtered at the driver level multicast frames are filtered by JunOS. The only problem I see could be on the performance side, as JunOS receives every multicast frames, even those not destined to it. However, I think this is not an issue for a simulated lab environments and it worked just fine so far.
If you feel you can do something cleaner, please don’t hesitate, you can still read one of the Intel manuals concerning the e1000 to have an overview of how complicated driver programming can be 
Conclusion
If you are IT guy (hope you are if you want to play with JunOS), you should be able to run JunOS on your PC without too many issues. I wrote this howto to be as complete as possible, showing how to compile and patch Qemu on 3 different operating systems, installing FreeBSD and JunOS. I encourage everyone to contribute to it by providing fixes, comments or any other help.
I’ve followed all the instruction but after “qemu -m 256 -hda olive-base.img -boot c -localtime -nographic -serial stdio”, nothing happen. No qemu window appear and I only can see “stderr” and “stdout” files in the Qemu folder.
stderr notepad shows:
qemu: could not open serial device ‘mon:stdio’
stdout notepad shows:
Unable to open driver: stdio
I’m trying to install olive in WinXP SP3 with qemu-0.11.0.patched.win32.
did anyone have the same problem as me?
Hi,
I always encounter this error (ELF Binary Type ’0′ Not Known). Do I missed something?
Thanks
Everything went smoothly following the directions exactly a written, till I actually got to pkg_add.
The VM complained about not enough space, saying I needed to change PKG_TMPDIR to a location that had at least 905682568 bytes. I cleaned out files I don’t need any more and made sure PKG_TMPDIR was pointing to /var/tmp. After clening out the files I had 1060060 K bytes free. So that should be enough. But kept getting same error.
O tried to run scp [email protected]:~/Desktop/jinstall-8.5R1.14-domestic-signed.tgz /var/tmp command but request gets timed out.
I put my PCs hostname instead of user, even i tried with the user i logged in with in my pc but still the request is getting timed out “ssh: connect to host 10.0.2.2 port 22: Operation time out”
I wasted my 3 days to resolved this don’t know y its not working.
I had put only “qemu -m 256 -hda olive-base.img -boot c -localtime ” command when booting olive image cause when i put “qemu -m 256 -hda olive-base.img -boot c -localtime \
-net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user” the qemu does’n start….
Please help guys
hi while trying to upload Junos iam getting following error.
scp [email protected]:xxxxx\jinstall \var\tmp
ssh: connect to host 10.0.2.2 port 22: Operation timed out.
I thought my antivirus firewall might be blocking the udp and tcp packets so disabled that and tried .. then also i was unsuccessful pl help here.
FTR, the pcap check in the patch is wrong.
Compiler barfs at not caster int return and also,
the $TMPC should be abefore the $LIBPCAP for the test compile to work.
Does anyone running this on a MAC OS X 10.6 know the replacement option for “-cdrom” in the QEMU command:
qemu -m 256 -hda olive-base.img -cdrom 4.11-RELEASE-i386-miniinst.iso \ -boot d -localtime
/Volumes doesn’t work. Using the mount point doesn’t work. I had this working on 10.5, but remember -cdrom didn’t work.
Any help is appreciated!
Thanks!
Hi, I’ve installed the olive by following the above procedure. However I’m facing currently two problems.
1. I configure the Juniper Router in GNS3 and commit changes bye using commit command. But it does not take effect. until unless I reload all the routers.
2. I’m unable to find serial interfaces, ATM interfaces & Sonet interfaces.
Can Anyone provide me the help regarding this.
Resolved JUNOS image upload problem :
My settings
- tap-interface with DHCP : ip taken 10.0.2.16
- Core FTP (mini-sftp-server) to upload your junos image (username=user,password=user)
then
sfttp [email protected]:jinstall-8.5R1.14-domestic-signed.tgz /var/tmp
from your freebsd VM
I’m not able to proceed with the following command:
qemu R1.img -m 96 -nographic -daemonize -serial telnet::2001,server,nowait \
-localtime -net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user
telnet localhost 2001
It produces a stderr.txt file containing:
qemu: invalid option — `-daemonize`
If I remove this option, it produces another error:
qemu: could not open monitor device `stdio`
Anyone else having this same issue?
Where do I put this command
“qemu-img create -f qcow2 olive-base.img 4G”
Hi to all,
I’ve tried to emulate JUNOS in GNS3 without success.
When I use the command “qemu -m 256 -hda olive-base.img -boot c -localtime \ -net nic -net tap,ifname=tap0 -net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user” (in Ubuntu 10.04) and after creating the tap interface with tunctl, I get the following message:
can’t add tap0 to bridge wlan0: operation not supported
I’ve tried to do it using the eth0 interface instead of wlan0, but I got the same results.
can anyone tell me what’s wrong??
Thanks!!
hi,
once olive is loaded, I configure an ip address for the en0 interface and do a commit but the check-out fails with this message:
vci/vpi/allow-any-vci is required
how is this possible if my interface is en0?
