Hello All, Is anyone successfully running MythTV in either a Dom0 or DomU? I have mythtv running with 4 PCI Hauppauge Nova-T DVB cards in a C2D system with a G33 chipset mobo under OpenSUSE 10.3. Everything works perfectly under the x86-64 kernel, as soon as I reboot into the Xen kernel I get picture tearing and eventually mythtv will crash, usually with a glibc malloc error. The best way I can describe the picture tearing is that it''s almost like the TV signal has become very weak, there are lots of mpeg artifacts on the screen like squares of static image and blocks of strange coloured pixels. I''m open to suggestions of other distros to try. Fedora Core 8 springs to mind as a possibility since it was only recently released so should have a very up-to-date version of Xen included. Kind regards, Steve. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I haven''t had any trouble with is. Distro is gentoo, on amd64.

It would be useful to keep this discussion on the list so that other people can benefit if they have a similar problem and search the list. Could you let me know what kernel version and xen version you are using. Also, what hardware are you using for your backend? I am especially interested in the motherboard, CPU and TV cards that you''re using. Ultimately, I would like to be able to pass the DVB cards to the DomU and run the backend in a DomU. This would make upgrading easier since I could take a copy of the current myth backend, upgrade it and if something doesn''t work I could simply boot up the original DomU. :-) Regards, Steve.> regards, > Bas > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Dear list, FYI: i have been running a mythbackend inside a domU for a long time now. I have "transported" 2 ivtv cards to this domU, and also a serial port for the external channel changer, that works just fine. I''m using the standard xen kernel for debian etch with no special kernel options or anything else. I did have to set some kernel options to get the domU kernel for the myth machine running. the options i used are : extra = "root=/dev/hda1 iommu=soft swiotlb=force" some version info: ii linux-image-2.6.18-4-xen-amd64 2.6.18.dfsg.1-12etch2 Linux 2.6.18 image on AMD64 ii linux-modules-2.6.18-4-xen-amd64 2.6.18.dfsg.1-12etch2 Linux 2.6.18 modules on AMD64 ii linux-modules-2.6.18-5-xen-amd64 2.6.18.dfsg.1-13etch6 Linux 2.6.18 modules on AMD64 ii xen-hypervisor-3.0.3-1-amd64 3.0.3-0-4 The Xen Hypervisor on AMD64 ii xen-linux-system-2.6.18-4-xen-amd64 2.6.18.dfsg.1-12etch2 XEN system with Linux 2.6.18 image on AMD64 ii xen-utils-3.0.3-1 3.0.3-0-4 XEN administrative tools ii xen-utils-common 3.0.3-0-2 XEN administrative tools - common files some notes: - before i did this 64bit version i tried to get this working on 32bit. However, it seemed that almost all ditributions are (were) switching to a PAE-enabled kernel. This kernel made the transfer of PCI cards very buggy. switching to 64bit and allocating enough memory on the domU (see swiotlb setting) solved these. - i''m using pciback hiding on dom0 - my pvr500 (dual tuner) is connected to a simple cable, but my PVR150 is connected to a skybox STB that is connected to my dish. It uses an external channel changer that works very fine in myth.(see here: http://www.dusky-control.com/ ) - don''t forget to install the ivtv drivers & firmware on domU & regenerate the initrd. - at the moment i''m using the xen emulated network adapter on domU. I normally have only 1 or possibly 2 frontends on at any one time. I do have the feeling that i''m close to the maximum transfer speeds for the emulated adapter. i think that setups that need more than 2 FE''s will also have to use an "exported, real" network card on domU for speed reasons. This could be related to the fact that i''m still using xen 3.0.3 and not 3.1. It seems like the 3.1 version will solve a lot of speed and i/o issues.
