Hi Andy!

It's been a while since I checked in on your project. Wow, it seems you've made quite a few improvements. BTW: thanks for adding that packet filter. I'll have to fire up the new image in my QEMU emulator and see how it goes. How's things in England?

Hi Andy,
Hope you are well in these times. Thanks for the update v.91 - will have to see if it'll compile for me OK.

Hi Andy, I used tcpdump on the host computer to grab some ethernet frames. I could follow the frames to verify that wget was doing everything correctly right up until the problem caused by not yet having SSL facilities. Then I thought I could be tricky and use wget to grab a README file from an ftp ...

Ah yes, looking now at the output from wget, it's obvious that the program is stopping due to the lack of SSL. I'm going to run tcpdump on the Gentoo host for now, since it'll filter the packets down to a manageable level. Should be fun to play with ... With tcpdump I often filter by port number and...

Andy, When I type host www.visopsys.org , I get the address response OK. Here's a pic: . visop-wget-1.jpg The sniffer is great. At my location tho - it really gets pillastered by all the devices I have around here. I suppose I could create an isolated subnet for it. If the sniffer could filter (for ...

The "unsupported" ethernet packet in the last pic is from my DVR - video IP protocol, so not an issue.

Hi Andy, Most humble apologies ... I received my brand new SSD, copied my qemu setup to it (along with Gentoo of course) - and ran Visopsys v.9 again. It worked without any interrupt issues. So - the issue was maybe something on my part. Anyway here are some pics of the first run ... visopsys-connec...

Well, currently I'm using native mode Qemu because my Odroids don't have the VT-x Intel hardware virtualization cpu extensions. For many operating systems, KVM would be a performance boost in Qemu. For Visopsys, I doubt that a person would notice much difference, but I could be wrong. My trusty Qemu...

Hi Andy, Yes, I used the command lines from the first page of this thread to run QEMU. Did you have the host networking set-up with the tun/tap, etc? I think QEMU may discard network args if it cannot find a hardware configuration that matches up with the args. In that case, maybe you'd be running w...

I'm reading that Qemu and almost all other virtualization software has plenty of issues with interrupt virtualizations. Qemu was mentioned specifically as having such issues prior to v2.9. I'll check the version I'm using. OTOH, Visopsys v0.82 worked OK with pcnet. I think you're using VMware?
