Does KVM PCI Device Assignment allow guests to access firewire?
by Wayne Feick 26 Jan '09

26 Jan '09

https://fedoraproject.org/wiki/Features/KVM_PCI_Device_Assignment The work on PCI device assignment looks like it might allow guests to access a firewire device. Can anyone confirm or deny whether that will be the case? Specifically, I currently run Linux as my desktop and Windows in a VMware guest for software like Adobe Premiere. This arrangement lets me do video editing, but not video capture from firewire since VMware doesn't support it. If KVM allows me to run a Windows guest that will be able to do capture video from the firewire port, I'll be switching away from VMware. Wayne.

Weekly virt status
by Mark McLoughlin 23 Jan '09

23 Jan '09

Hey, I've started sending out a "Fedora Virtualization status report" to folks at Red Hat to keep people informed about what's going on. Dan Berrange suggested I send it here too ... not sure why I didn't think of that myself. Feedback or suggestions very welcome. Cheers, Mark. The Fedora 11 Alpha Freeze happened this week, but unfortunately things we in great shape. Wait, that's a good thing! Well, things were in such great shape, there was going to be too big a gap between the freeze and release, so rel-eng has decided to try the freeze again next week. So it now looks like: 2009-01-27 Alpha Freeze (4 days) 2009-03-03 Feature freeze (39 days) 2009-03-10 Beta Freeze (46 days) 2009-04-14 Final freeze (81 days) Alpha Freeze, Take 1 ==================== We had a bunch of blockers to resolve before the freeze. Rawhide installs had all sorts of issues, mainly in anaconda. However, just because they're anaconda bugs doesn't let us off the hook. Some of these were virt specific, and the existance of any of these blockers meant that we weren't rigorous enough about testing and filing bugs against rawhide. Hopefully we'll do better for the rest of the release cycle. Some of the anaconda blockers: rawhide anaconda stage1 x86_64 images missing virtio drivers https://bugzilla.redhat.com/480307 anaconda loader crashes when configuring a network interface https://bugzilla.redhat.com/479707 rawhide anaconda vnc install failure https://bugzilla.redhat.com/480308 No networking configured after rawhide kickstart install https://bugzilla.redhat.com/480769 And we had one fairly random libvirt blocker caused by a change in chkconfig: libvirt default network not enabled at install time (chkconfig regression) https://bugzilla.redhat.com/480805 Alpha Freeze, Take 2 ==================== Cole is working on new virt-manager and virtinst releases. Will we make the freeze this time? We didn't get the libvirt 0.6.0 release done this week, but maybe in time for next Tuesday? On the KVM side, we should aim to get a resolution either way for the unsynchronized TSC issue: https://bugzilla.redhat.com/475598 Avi, Gerd, Glauber and Juan have all been actively looking at this. Looks like we're close to a patch. But at this point, we need to decide either to include the patch in the alpha or disable kvmclock temporarily. fedora-maint-list ================= We created a fedora-maint-list to allow people to easily watch what's going on with all virt related packages in Fedora. Sign up here: http://www.redhat.com/mailman/listinfo/fedora-virt-maint/ and also add fedora-maint-list(a)redhat.com to your bugzilla watch list: https://bugzilla.redhat.com/userprefs.cgi?tab=email If you want to filter these mails, try this: Sender is bugzilla(a)redhat.com X-Bugzilla-Reason is None X-Bugzilla-Watch-Reason contains fedora-virt-maint(a)redhat.com That way you can keep them separate from mails sent because you were directly cc-ed on a bug. Tracker Bugs and Queries ======================== See this wiki page: https://fedoraproject.org/wiki/Virtualization_bugs We now have virt tracker bugs for F11: https://bugzilla.redhat.com/showdependencytree.cgi?id=F11VirtTarget&hide_re… https://bugzilla.redhat.com/showdependencytree.cgi?id=F11VirtBlocker&hide_r… and also a bunch of pre-canned bugzilla queries for all the different virt packages. F11 Features ============ These features have been posted to the wiki: https://fedoraproject.org/wiki/Features/VirtVNCAuth https://fedoraproject.org/wiki/Features/KVM_PCI_Device_Assignment https://fedoraproject.org/wiki/Features/KVM_and_QEMU_merge More drafts are in progress. Fedora 10 Kernel ================ 2.6.28 is coming soon to F10: http://www.redhat.com/archives/fedora-devel-list/2009-January/msg01302.html An initial build is already in Koji if people want to give it some early testing. bugs ==== The page: https://fedoraproject.org/wiki/Virtualization_bugs has a bunch of bugzilla queries. I'll quote the number of open Fedora virt bugs here from week to week to track progress.

Unable to install kvm paravirt guest
by Julian Sikorski 23 Jan '09

23 Jan '09

Hi, I am trying to install i386 paravirt rawhide kvm guest (using xenner) into a Fedora 10 x86_64 host. I use the following command: virt-install --paravirt --os-type=linux --location=http://ftp.ps.pl/pub/Linux/fedora-linux/development/i386/os/ --name=pararawhide-i386 --vcpus=1 --file=/var/lib/libvirt/images/pararawhide-i386.img --accelerate --nonsparse --ram=512 --file-size=15 Unfortunately, anaconda fails when it is supposed to fetch install.img, it says there was an error configuring the network connection. The log is attached. Do you have any ideas what is wrong here? Regards, Julian

xenner service not started automatically
by Julian Sikorski 23 Jan '09

23 Jan '09

Hi, It seems that the xenner service is not started when you attempt to install a paravirt guest. It took me a while to figure out that it needs to be started manually. Is it possible to make that service get started on demand? There is a bug on that, #462120. Regards, Julian

When you minimize paper-based activity and work within a digital environment, you trim overhead costs by reducing reliance on paper, streamline workflow with quick access to information, and protect patient records with strict user-control. The burden of administrative and clinical documents in a medical practice is considerable. Busy offices lead to inaccessible administrative documents and charts; whether misplaced, lost, or in use by another staff member. Physician practices continue to seek a solution to reduce or eliminate the increasing volumes of paper within their organizations. The optimal product would eliminate the issues of overcrowded office space and storage facilities as well as the problems associated with paper medical records such as lost or misplaced patient charts, patient EOBs, etc. Medical staff and providers demand a user friendly HIPAA compliant solution that enhances patient care, and reduces cost of operations while increasing revenue and generating a rapid return on investment (ROI). eDocHealth is a cost-effective way to meet those needs, by automation of administrative and clinical documents management. eDocHealth does not force you to change your office workflow, instead, it can adapt to it or be configured for “best operational practices”. eDocHealth can work in conjunction with your Practice Management software and Electronic Medical Records software (EMR/EHR). In most cases document management solutions are better suited to manage medical records than traditional EMR/EHR. It is a non fact that document management solutions have near 98% implementation success while traditional EMR/HER solutions are more challenging endeavors. www.recordsreduction.com PO Box 3322, Matthews, NC 28106 http://app.streamsend.com/private/tF8d/2bm/tbuVb85/unsubscribe/2511712

OK, doing here. All my tryes to create an functional virtio initrd failed on kernel-PAE, when system was booted as "ide" machine. Boot success happened with kernel (non-PAE) and after boot I was able to uninstall kernel-PAE and reinstall it. After this change there are all required modules installed and kernel-PAE boot with virtio drivers (disk and net).

This is probably crazy talk, but the freeze for F11 Alpha is today if you thought it was possible to do these releases sooner. Cheers, Mark.
