Stuck keyboard/trackpad; Dell Latitude D630 laptop; CentOS 6.4 DOM0
As I tried to jam into the subject line, I''ve installed Xen hypervisor on a Dell Latitude D630 laptop, using the Xen4CentOS repository. I have no problem using the trackpad and keyboard when I boot directly into CentOS. However, when I boot into Xen with a CentOS 6.4 DOM0, the keyboard and trackpad will only work briefly. After a little trackpad movement or a few keystrokes, the trackpad and keyboard become "stuck" in their current state, i.e. I can''t move the cursor or enter any new keystrokes (nor will a key up register; often it will become stuck with one key down). If I use a USB mouse and keyboard, they work fine. I can''t find any enlightening information in any of the logs in /var/log/xen/, nor in dmesg output. Has anyone had similar issues with serial or PS/2 devices in DOM0? I''ve been Googling and experimenting for hours with no luck. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
Hi. I have a debian x64 bit dom0, xen 4.3.1. I have a SUNIX PCI card wich provides 8 SERIAL ports. I''d like to share this pci device among more guest oses (PV linuxes and a HVM windows). Is that possible somehow? (I already could successfully do pci passthrough for one PV guest.) Do you have other ideas how to solve this? For example is it possible to share one serial port with one OS and an other with other (So I''d like to passthrough only some device files, not whole pci devices)? Like: dom0 /dev/ttySNX0 -> domu linux PV dom0 /dev/ttySNX1 -> domu Windows HVM -- Éliás Tamás \ Thomas Elias ETITEAM KFT, Ügyvezető \ ETITEAM Ltd, Manager Okleveles mérnök-informatikus (MSC) Master of Science in Information Technology (MSC) Certified Ethical Hacker (ECC963382) Tel.: +3630/497-1626 ; Web: http://etit.hu OpenPGP public key: http://etit.hu/doc/et-pub.asc ** A jelen elektronikus levél bizalmas és tartalmazhat olyan információt, amely kizárólag a címzettnek szól.

What does lspci show? NB, thinking about PCI passthrough in terms of /dev/device files will mislead you -- you need to think in in terms of the PCI bus addresses shown in lspci.
