Moves the libxml2 bits to a separate xmlapi file and class, a bunch
of cleanups to xmlbuilder internals dealing with XML stuff.
The main point is to experiment with different XML library impls,
since libxml2 is unfun to deal with and we are having python3
issues like
https://bugzilla.gnome.org/show_bug.cgi?id=776815
Currently the domain CPU class has a child property like:
siblings = XMLChildProperty(_CPUCellSibling)
If a user wants to add a new sibling, we add a convenience function:
def add_sibling(self):
obj = _CPUCellSibling(self.conn)
self.add_child(obj)
return obj
Rather than require every child property to define a similar matching
helper function, this adds infrastructure in xmlbuilder to do this
generically for every child property. Now callers can do
obj = guest.cpu.siblings.add_new()
In Python 2 the raise command can take 3 objects as arguments which
are used to specify the exception to be raise as well as detailed
information and traceback [1].
In Python 3 the sintax is changed and now the keyword "from" and
"with_traceback" keyworkds are used to specify this information. [2]
Example which has the same behaviour for both Python 2 and 3:
try:
a = 1/0
except Exception:
import sys
err = sys.exc_info()
try:
raise Exception("Test")
except:
pass
if sys.version_info[0] == 2:
exec("raise err[0], err[1], err[2]")
else:
raise
Add vcpupin support to virt-install so that it can create guest
domains with statically allocated vcpu pinning towards a given cpuset.
Syntax: to pin vcpu=0 to cpuset="1,3" and vcpu=1 to cpuset=2
--cputune vcpupin0.vcpu=0,vcpupin0.cpuset=1,3,vcpupin1.vcpu=1,vcpupin1.cpuset=2
generates below XML description for the guest domain.
<cputune>
<vcpupin vcpu="0" cpuset="1,3"/>
<vcpupin vcpu="1" cpuset="2"/>
</cputune>

If we detect that the UEFI image is build to require SMM feature we
should configure the guest to enable SMM feature and set q35 machine
type. Without this user wouldn't be able to boot the guest.

This element controls hot(un)plugable memory for the guest in
addition to the initial memory configured by <memory> element.
One has to configure <maxMemory> and guest numa nodes using <numa>
element to enable hot(un)plug of memory modules.

When an error occurs when the VM creation wizard tries to start the VM,
it's then not possible to press again the "Finish" button to try again
to start it, as this errors out with:
Traceback (most recent call last):
File "/home/teuf/redhat/virt/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper
callback(asyncjob, *args, **kwargs)

raise RuntimeError(_("Domain has already been started!"))
RuntimeError: Domain has already been started!
This is caused by code introduced in commit fc6778 which does not reset
self.domain to None when an exception is caught.

This is for xml like:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
</devices>
<qemu:commandline>
<qemu:arg value='-newarg'/>
<qemu:env name='QEMU_ENV' value='VAL'/>
</qemu:commandline>
</domain>
Requires some extensions to the xmlbuilder infrastructure
Since we only attempt to add a default USB controller for x86, match
it by only trying to add redir devices on x86 as well. Fixes a uitests
failure for ppc testing, since the test:/// driver doesn't add an
implied USB controller, and libvirt now validates that one was provided.
Currently we hardcode these defaults for installing VMs:
<on_poweroff>destroy</on_poweroff>
<on_reboot>destroy</on_reboot>
<on_crash>destroy</on_crash>
And these for post-install config:
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
But this has some issues. on_crash=restart is problematic in that most
configs don't support it, and some like virtuozzo actively reject it.
Additionally this we should leave as much to libvirt defaults as we
can, which are more sensible in this case.
Drop everything except setting on_reboot=destroy for the install time
case (which is required for our config changes). Since on_poweroff
and on_crash already default to 'destroy', the install time config
is unchanged, and the post-install config now on_crash=destroy instead
of 'restart'.
The s390 on_crash=preserve workaround is dropped, which was intended
to avoid a reboot loop caused by on_crash=reboot
This includes adding an smbios sub-element to the guest os element and a
sysinfo sub-element to the guest. The sysinfo sub-element contains the SMBios
specific data.
