by silviu d
Hello,
I was wondering if there is a way to execute commands from dom0 into domU
without loging into domU with ssh.
thanks

Was xenstored.service enabled? That should have set up the environment
correctly.

One of the experiments I was intending to do with that build was to see if
xen would would work with Fedora's qemu. As you have just discovered the
answer is no, though the tools configuration option allowing you tell xen
where to find it seems to work. If you uninstall the qemu-system-x86
package or add the line
device_model_version="qemu-xen-traditional"
to your configuration file then your hvm guest should boot.

Fwd: Fedora 21 Virt Test Day is Thu Sep 25!
by Cole Robinson
Hey xen folks, while much of the UI test cases are specific to KVM, never
hurts to have people show up and test what they are interested in, we will
have virt-manager and libvirt people on hand if you hit issues.
Thanks,
Cole

Hey all,
The Fedora 21 Virt Test Day is this coming Thu Sep 25. Check out the test day
landing page:
https://fedoraproject.org/wiki/Test_Day:2014-09-25_Virtualization
If you're interested in trying out some new virt functionality, there's step
by step instructions for:
* Q35 Chipset
* Import AArch64 image as a VM on x86
* Install VM using OVMF/UEFI
Even if you aren't interested in testing new features, we still need you! The
test day is the perfect time to make sure your virt workflow is working fine
on Fedora 21, as there will be several developers on hand to answer any
questions, help with debugging, provide patches, etc. No requirement to run
through test cases on the wiki, just show up and let us know what works (or
breaks).
And to be clear, while it is preferred that you have a physical machine
running Fedora 21, participating in the test day does NOT require it: you can
test the latest virt bits on the latest Fedora release courtesy of the
virt-preview repo. For more details, as well as easy instructions on updating
to Fedora 21, see:
https://fedoraproject.org/wiki/Test_Day:2014-09-25_Virtualization#What.27...
If you can't make the date of the test day, adding test case results to the
wiki anytime next week is fine as well. Though if you do plan on showing up to
the test day, add your name to the participant list on the wiki, and when the
day arrives, pop into #fedora-test-day on freenode and give us a shout!
Thanks,
Cole
