Hi everyone!

I'm pretty new to OSX and my goal is to install an instance of OSX in a virtual environment on my Linux host. I got myself iPC 10.5.6 and iDeneb 10.5.6 images and first of all failed to install them with both VirtualBox and vmWare.

However, the installation in qemu worked very well and the performance of the OSX guest system is excellent!

There is only one issue: The emulated network card (RTL8139) is not working. It is recognized by OSX (green icon in System Settings, Network Utitilty says Manufacturer Realtek Model 8139). I also tried every other virtual network device qemu provides, but they don't even get recognized.

Qemu provides a DHCP server and should get my OSX an IP Adress, but the DHCP request times out and OSX gets a Self-assigned IP which again results in no connectivity. Static IP configurations is not working either.

The network adapter seems to be up for just a very short time. I dumped all the traffic of the virtual network adapter to a file and analyzed it with wireshark: First, OSX sends a DHCP Request, qemu responds with a DHCP Ack. They negotiate to 10.0.2.15. However, after that, no more packets are transmitted in both directions and the negotiated IP address is not assigned to en0.

My command line for starting qemu is:


Now here comes the intersting part: When i launch qemu with qemu-system-i386, the network driver is working and I can access the Internet from commandline. But the system is terribly slow and practically unusable (which makes sense as there is no hardware acceleration).
Also, Safari crashes upon launching, which it doesnt when running in x86_64 mode.

I tried several AppleRTL8139Ethernet and PCGen kexts off the Internet and from your forums, but the problem remains the same.

I'm really stuck here and your help would be greatly appreciated!

Thanks in advance!

Pinging an outside host speeds up networking dramatically here. Open a terminal in Mac OS X and run this command:

ping 10.0.2.1

Keep this running while surfing with Safari.

Hi, I have EXACTLY the same problem; iPC 10.5.6 also. I can't make the network work, it's driving me crazy.
Currently I'm still playing with it, so will report back if it works. In the meantime, if someone knows how, please tell

See you later !

Well, I was able to make a (slow) connection using serial.



Then in OSx I configured "Built-in Serial Port" as:


on the host:



I can ping and use the web with a proxy (4kb/s ~_~). Will try to make the **** real network work tough

FTR I finally made a dhcp/user mode connection, but it's as slow as serial.



OSx recognize the usb network and configure it automatically, sadly at 4kb/s ~_~

Same problem here.
After a successful installation of osx (ideneb 1.6 10.5.8) under qemu I spent some time in trying to make network working without luck.

The RTL8139 card is recognized but dhcp doesn't work (setting a manual address doesn't work either). With qemu tap networking it seems even more close to working, I was able to see an IP address successfully assigned from dhcp (a "real" dhcp, non the virtual qemu one), a working ping to the gateway, but nothing more... trying to ping an external address or to navigate using safari still does not work.

I also tried all the other qemu emulated networ adapters, still no luck:

• ne2k_pci -> Realtek RTL-8029(AS) -> not detected, no kext found
• i82551,i82557b,i82559er, -> qemu crashes with "eepro100.c:1514: nic_receive: Assertion `size <= rfd_size' failed" (also tried patching the qemu sources, removing that assertion ends up in a kernel panic)
• e1000, -> 82540EM Gigabit Ethernet Controller -> not detected by the standard driver. Also tried the SmallTree driver (both kext with fixed ids)
• pcnet -> amd 79C970 [pcNET32 lance] -> not detected, no kext found
• virtio -> not detected, no kext found

anybody had more luck?

hey maticta!

thanks for sharing! having not tried to use the usb adapter makes me feel like an idiot

I can confirm the usbdevice working, but just as you mentioned at very slow speed!

cheers!

Hi, moongose, sorry for bad english.
My goal is the same but i try to install on qemu and fail! Hi have tried with iDeneb 1.5.1 and iPc. I think my problem is that i'm not able to found a good guide to do this, with all necessary steps and qemu and boot parameters. Can you post your qemu complete instruction used for installation from iso and the boot parameters used after?
Thanks!

hi dkano,

the qemu command line is like mentioned above, of course with the iPC / iDeneb image attached to cdrom:

Of course you have to create the disk file in advance (qemu-img create).

After that, the installation is pretty straight forward. Read the instructions that come with iPC / iDeneb and in my case the installation succeeded (I needed two attemps because I didn't read the instructions properly, so make sure you do ;-)

Also search this forum for guides. Even if they are not qemu related, they can also help.

Cheers

Well, yesterday I upgraded my Debian Sid and qemu 0.11 was available with kvm enabled. Tried again and now it works ! Well, sort of



It works with dhcp, but network is slow. If you open a terminal and run "ping 10.0.2.2" it gets a little faster (about 12kb/s downlading adium in my case), just like Hein Bl�d said.
BUT, running various pings in parallel give even more speed, with 6 pings I'm almost at the top of my internet connection (I have only 512kbps). I think I'm going to make a script running in background for this.

Anyway, now that rtl8139 works I think I'm going to try bridge networking and see how it goes =)

Edit: I upgraded from kernel 2.6.30 to 2.6.31.5 the same day, so maybe the issue was solved by the new kvm module
Edit2: Nop, tried with the old qemu and still doesn't work, so it's something that was solved in qemu 0.11 and not in the kvm module
Edit3: Instead of multiple pings, just using "ping -q -i 0.1 10.0.2.2" is enough for getting full network speed (at least for me). Now is time to play =)
