If you are crashing xen then that is a fault in the base dom0 system, not the guest, as nothing the guest can do should crash the hosting system (most likely in your xen build or the dom0 kernel). However you don't say anything about the base system, so it isn't clear this is a Fedora problem at all. Roger, the dom0 system is centOS 5.6. However, the reason I think it may be a Fedora bug is that this behavior is not replicated when performing the same task in HVM's running CentOS or Scientific Linux. Also, this is replicated across different builds of xen ranging from xen4.0 to 4.2. Granted, I will try to test it out on a more updated install (OS) maybe even a fedora dom0 to see if it is replicated. Also, I have filed a bug with xen on this issue, just to cover the bases. That being said, you may have a point being that the fedora install in my setup is the only one running a 3.0+ kernel, as both centos and scilinux are not there yet. So this may be kernel level issue, as opposed to a specific distro. I'll test it out. I just find it odd that it happens only when installing/updating the package, and only with fedora, but once everything comes back up afterward, it works just as smoothly as ever (after cleaning up the rest of the transaction).

That doesn't make it a Fedora bug. You are just finding a xen or dom0 bug that is triggered by a Fedora guest but not RHEL clone guests, which might be due to the later kernel or something else in Fedora. I agree you should try to reproduce the bug with a later dom0 kernel as I doubt there would be much interest in a bug that only occurs with an old RHEL dom0 kernel. It might also be worth trying a CentOS 5.8 in case it is a bug that has been found and fixed (there are some svm/HVM fixes listed in the changelog, though they may be for the xen hypervisor shipped with their kernel). This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
