[Fedora-xen] Newbie Virt Questions and comments on wiki/Docs/Fedora8VirtQuickStart
I am trying to migrate my virtualization infrastructure from a pure Xen implementation to the more versatile Fedora virt-manager Xen/KVM environment. While doing this, I have hit some snags related to areas in which pure Xen documentation no longer applies due to the presence of lib-virt et al. First a minor comment on the Fedora8VirtQuickStart (draft I know): The section:> Building a Fedora Guest System using `virt-manager`no longer applies because between Fedora 7 and Fedora 8 there no longer appears to be a "New" button or a "File New" option in virt-manager. It would appear that the only way to create a DomU is by way of virt-install. Now, my problem. I have successfully created fully functional guest VMs which work perfectly in every way but, in the context of lib-virt and virsh, I can not figure out how to get the guest machines to be started automatically when the host machine boots. In a pure Xen environment, you symbolically link the "/etc/xen/<vm-config>" file into "/etc/xen/auto". After using virt-install to create the guest, the domain configuration files end up over in "/var/lib/xend/domains". I have tried to symbolically link the whole domain directory to "/etc/xen/auto", I have tried to link the configuration file to "/etc/xen/auto". I have tried to export the configuration as XML using virsh and then put that under "/etc/xen/auto". Nothing works and there is no indication from the xend.log that it is even trying to start the guest domains on bootup. I also tried to use: virsh autostart <domain> and get the error: libvir: error : this function is not supported by the hypervisor: virDomainSetAutostart So, my question is, is it possible to properly manage the start up and shut down of guest domains on host start up and shutdown or is that just not supported yet. If there is a way to do this, it would be a very helpful section to add to the Quick Start document because I would expect anyone migrating from a pure Xen environment to have the same issue. Google reveals that several have asked this question in the past on Fedora 7 etc and I have not seen any answer other than people suggesting to link the configuration file under "/etc/xen/auto". Thanks, Aaron
In my previous post, I was asking questions about how to get guest VMs to cleanly shutdown and start back up when the host shuts down and starts back up.> Newbie Virt Questions and comments on wiki/Docs/Fedora8VirtQuickStartI have made some progress on this issue by complete accident. Previously I had a Fedora7 guest stored in an LVM partition. I just tried a Fedora8-RC3 guest stored in a regular file. Now the behavior is that if the guest is running when the host is shut down, it appears to try to start it back up after the host boots back up. BUT, the guest restore fails with the following: I would greatly appreciate any tips on how to stabilize this environment to get clean guest shutdowns and start ups when the host shuts down and starts up. Thanks in advance.> [2007-11-07 09:45:40 2414] INFO (SrvDaemon:338) Xend Daemon started > [2007-11-07 09:45:40 2414] INFO (SrvDaemon:342) Xend changeset: unavailable. > [2007-11-07 09:45:40 2414] INFO

Edit your "/var/lib/xend/domains/<domain-uuid>/config.sxp" file. Look for the lines containing (on_xend_start ignore) (on_xend_stp ignore) and change them to be (on_xend_start start) (on_xend_stop shutdown) This will restart the domain when the xend daemon starts. Mine still fails for the case where I "reboot" the host instead of shutdown, powerup because it seems like it can not restart from the virtual machine image saved in "/var/lib/xen/save". I tried to post a log file with that failure to this list but it looks like the e-mail was to large to post or something because it hasn''t shown up in this list yet. At least now I have a solution which will work when my UPS shuts down the server during a power outage. -- Aaron

Figured this out - They had to remove the global new button, because the UI now allows multiple hypervisor connections. So you need to be able to have a new button that is linked to a specific connection. The button is now there for each hypervisor on the right side. I didn''t see the button before. If you right-click, that''s a second way to access it. I don''t think it will be too hard to make the button more obvious. -Sam> >

The issue is described bellow:
When running Windows Vista ultimate in a domain with
two vcpus, and then do a heavy disk IO in domain0, the
Vista will blue screen with such message "a clock
interrupt was not received on a secondary processor
within the allocated time interval" with Bug Check
0x101.
This bug can always be reproduced by running the
memory testing from Linux Performance Testing suite in
domain 0. Note: domain 0 must use the hard disk as
swap place.
I need some helps from Linux expert.
Why the system is very slow when you access the hard
disk frequently under Linux?
Does it allowed to preempt when do disk i/o access
from 2.6.18 Linux kernel?
The detailed process of disk I/O handler under Linux.
The interrupt status, the cpu status and buffer lock

If you think I was making sarcastic comments, you''ve mistaken my intent. It was heartfelt, and on reflection, fair comment. I really do not like the UI design. As for patches, not from me. I can struggle out a bit of Perl if I must, but Python has me beaten. My time''s better spent helping people come to terms with getting their Linux systems working. -- Cheers John -- spambait 1aaaaaaa@coco.merseine.nu Z1aaaaaaa@coco.merseine.nu -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-)
