I tried to fill this gap by writing vvfat a long time ago, but people seem to hate it. Actually, I think vvfat is another useful feature (thanks for the work you put into it), but I also think it's not trivial to keep the device in sync while qemu is runnning and writes can occur from the host to the shared directory and from the guest to the virtual hdd / removable medium (hotplug support is needed from the guest or things are likely to go out of sync). With FTP you'd just refresh when the ftp-client asks for a refresh. Much easier to handle this ;) Additionally linux is able to mount FTP as well (using FUSE or LUFS) thou this is a bit of a hack. In my opinion the versatility of qemu is one of its best features. Therefore I think its good to add various helpers to it, so you can choose the one, which is suited best for your setup/problem.

Hi Rene, Your HowTo is quite nice and might be enough for most users, but it depends on modifying the host-system, which needs admin/root privileges. An internal virtual FTP server which serves a directory of the host might be slower, but it would not need any changes on the host side.

Could you point me to bugtracker or person who knows something about ppc in Qemu? Bug reporting, patch submission and feature/development discussion is all done on this mailing list. Additionally you can get help in irc (#qemu on freenode) and the user forum. Now to get your problem pinned down, you should try to check if it prevails with the current cvs version of qemu.

To give some feedback as well, I like the idea of dynamic hardware as qemu can become even more versatile than it is right now.

I can understand that the problem is serious.

But if you insist on using dosemu inside of qemu, then you'll go best installing some minimal linux into the qemu system emulation and get dosemu for this system. If you only want to run dosemu on a non-supported os (witch is supported by qemu) then you could use the same method which applies to wine on ppc: * User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API emulator (http://www.winehq.org) or to ease cross-compilation and cross-debugging.

How can activate UDMA mode for hard disk ? I don't think you'd get any advantage of activating DMA inside the qemu guest-OS, as qemu has to proxy all rw-access into a file anyway, unless you pass an actual device/partition to qemu. Besides qemu is emulating the complete pci bus, which cannot use features of actual hardware in the machine (e.g. your hdd or features your chipset provide). I guess it would be possible to emulate uDMA inside the vm, too, but it's likely to even slowdown the emulation.

Re: [Qemu-devel] Looking for an easy way to exchange data bidirectional between host and guest (including some suggestion)
Not quite, but TFTP by protocol design limits filesize to 2^16-1 blocks of 512 bytes or 32 MB minus 512 bytes (33553920 bytes). Well, if this is the case FTP should realy be added as an alternative protocol. And the more I think about vvFAT, the more I think it's too complex to get this working bidirectional and secure in regard to file integrity.

Re: [Qemu-devel] Looking for an easy way to exchange data bidirectional between host and guest (including some suggestion)
- no ide-channel is blocked (unlike vvFat) I don't believe this is a major issue. Alias, vvFat is readonly and anyways not suitable for the purposes of every OS (e.g. copy from Linux guest to Linux host, preserving ownership). Well for the current project I'm working on, I'm running short of ide-channels in some situations: I've one ro-diskimg containig the OS then there is an exchangeable ro-discimg containig programms for different purposes, then there is the rw-diskimg where the user can store his information. And sometimes a software needs to have a cd in the drive as well. Like I said, modifying TFTP for R/W would be a good option. It's already there, the miminalists can't complain about having it removed (e.g. it may one day be used to support virtual netboots), and one can use ftp clients for the tftp server (I think). Well the TFTP-server should get r/w, too, but if I get it right you'd have to access the data on the guest from the host, which might lead to situation where users shutdown the guest and then try to get their (then lost) data from it via TFTP, which has to be installed on the host. The Samba-wrapper does not work on Win-on-Win situations But windows host has native SMB support. Surely the wrapper could be altered to support using SMB via win32 ? I guess it could be modified, but then you'd have to share some directories via smb either on the host or the guest, which would be some additional requierement, which would destroy an out-of-the-box use (insert DVD in any workstation on the lan, get your working sandboxed virtual desktop) Have a nice day, Jan ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
[Qemu-devel] Looking for an easy way to exchange data bidirectional between host and guest (including some suggestion)
Ok, I talked about this issue in irc lately, but as this list will have a larger audience I'll post this here as well. So here is the (cleaned) log: What I want: jamasi some feature I'm really missing is: a v(S)FTP sever inside the emulated network offering a local folder of the host for R/W-access. pbrook If you have sshd running on the host, you can just connect to that. jamasi win-hosts usually dont have sshd running. And it would be really appreciated, if it would work with user-net. An idea how this could be done: *jamasi so basically you could just take some tiny ftp-server source and put it into qemu and then add a command-switch for the directory to share. username and psw could be qemu:qemu or even left blank.* Why the current options are no real alternative so far (either linux-only or read-only): MadMerlin can't qemu do file sharing via samba already? iamlost jamasi: it already exists. iamlost jamasi: virtual disks pbrook iamlost: THat's only readonly. iamlost pbrook: virtual floppys or virtual cdroms could be used to transfer data from host to guest while guest is running. pbrook Like I said that's still only readonly. iamlost pbrook: host could read virtual hard disk from guest to transfer data in other direction pbrook Huh? iamlost pbrook: so, despite being readonly, it can be made two way pbrook How do you do that? iamlost pbrook: in linux, via lomount. iamlost as long as u mount it read-only in the host, u shouldnt have any problems. pbrook And if you're on window, or don't have root access? pbrook If you're on liux you probably already have sshd running, so can just use sftp. iamlost pbrook: im sure theres something similar (like Daemon Tools) for windows... jamasi I think the vvFat-approch is pretty nice, but it blocks an ide-channel and it somehow feels more dangerous than a simple ftp-server. pbrook iamlost: daemon tools only does cdroms. pbrook There are third party lomount-like things, but they tend to be use unfriendly, and not very well supported. iamlost oh pbrook And you still need admin access. iamlost :/ pbrook Plus to do that you have to shut down the guest. iamlost well...u can still use virtual floppies... pbrook How? iamlost works fine as long as data is small enough. iamlost its a little painful to use tho. pbrook Very paindul, and how exactly do you mount those on a windows host? iamlost when the guest writes data to a virtual floppy and ejects it, u then write the image onto a real floppy iamlost and then read that iamlost i know there are tools like rawwrite.exe which can do that. pbrook Most new machines don't have floppy drives. pbrook Plus it's painfully slow. *jamasi I think introducing some ftp-server is far less pita. alternatively a webDAV-server would be an option.* iamlost jamasi: there was a tftp sever patch some time ago pbrook ftp is certainly the lowest-common-denominator simplest option. jamasi this was readonly, too. jamasi I'm looking for a way to exchange data with the host, without shutting-down the guest and without needing any special conditions for the host. jamasi and for me an integrated ftp-server serving some host directory seems like the best way to implement this. jamasi sadly I'm really unskilled in c(++). Otherwise I'd try to implement this. So to implement the idea one would need to get the source of a tiny gpl/bsd-ed FTP-server (does not need to have any fancy things like usermanagement, SFTP or TFPT, ratio, quota,...), bind this to the emulated gateway and create a new cmd-line-option to set the served directory. A reread of the directory would be issued on a refresh-cmd from the ftp-client on the guest. Thanks for reading this. I'd really appreciate a patch for this functionality, which should then be merged into cvs, imho, as this could be an easy interface for fileexchange.
