Currently, libvirtd will start a dnsmasq process for the virtual
network, but (aside from killing the dnsmasq process and replacing it),
there's no way to define tftp boot options.
This change introduces the appropriate tags to the dhcp configuration:
<network>
<name>default</name>
<bridge name="virbr%d" />
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<tftp root="/var/lib/tftproot" />
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
<bootp file="pxeboot.img"/>
</dhcp>
</ip>
</network>
When the attributes are present, these are passed to the
arguments to dnsmasq:
dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^
from <tftp /> from <bootp />
At present, only local tftp servers are supported (ie, dnsmasq runs as
the tftp server), but we could improve this in future by adding a
server= attribute.

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

Latest upstream QEMU can be built with Xen support, which introduces

The commit cb51aa48a7 "Fix up connection
reference counting." changed the driver closing and virConnectPtr
unref-logic in virConnectClose().
Before this commit virConnectClose() closed all drivers of the given
virConnectPtr and virUnrefConnect()'ed it afterwards. After this
commit the driver-closing is done in virUnrefConnect() if and only if
the ref-count of the virConnectPtr dropped to zero.
This change in execution order leads to a virConnectPtr leak, at least
for connections to Xen.
The relevant call sequences:
virConnectOpen() -> xenUnifiedOpen() ...
... xenInotifyOpen() -> virConnectRef(conn)
... xenStoreOpen() -> xenStoreAddWatch() -> conn->refs++
virConnectClose() -> xenUnifiedClose() ...
... xenInotifyClose() -> virUnrefConnect(conn)
... xenStoreClose() -> xenStoreRemoveWatch() -> virUnrefConnect(conn)
Before the commit this additional virConnectRef/virUnrefConnect calls
where no problem, because virConnectClose() closed the drivers
explicitly and the additional refs added by the Xen subdrivers were
removed properly. After the commit this additional refs result in a
virConnectPtr leak (including a leak of the hypercall file handle;
that's how I noticed this problem), because now the drivers are only
close if and only if the ref-count drops to zero, but this cannot
happen anymore, because the additional refs from the Xen subdrivers
would only be removed if the drivers get closed, but that doesn't
happen because the ref-count cannot drop to zero.
The fix for this problem is simple: remove the
virConnectRef/virUnrefConnect calls from the Xen subdrivers (see
attached patch). Maybe someone could explain why the Xen Inotify and
Xen Store driver do this extra ref-counting, but none of the other Xen
subdrivers. It seems unnecessary to me and can be removed without
problems.

This implementation stores the secrets in an unencrypted text file,

The algorithm is quite simple:
If the emulator matches a guest's domain:
if domain has machine type info:
check the domain's machine type info
else
check the guest's default machine type info
else if the emulator matches the guest's default emulator:
check the guest's default machine type info
The previous implementation was incorrectly falling back to the default
machine type info if the domain's machine type info didn't have an
alias.
* src/qemu_driver.c: simplify and fix qemudCanonicalizeMachine()
Currently we only probe the main qemu binary for machine types, but we
should also probe the kvm binary.
* src/qemu_conf.c: probe kvm binary machines in qemudCapsInitGuest()
We need to look at all the domain infos in guest capabilities, not
just the defaults.
In order to allow that, split out a qemudGetOldMachinesFromInfo()
from qemudGetOldMachines(). We'll make more use of it in the next
patch.
* src/qemu_conf.c: split out qemudGetOldMachinesFromInfo() from
qemudGetOldMachines()
This doesn't have any affect on the current tests because we don't have
any machine aliases in the current test data.
* src/qemu_conf.h, src/qemu_driver.c: expose qemudCanonicalizeMachine()
for the tests
* tests/qemuxml2argvtest.c: canonicalize the machine type
After the mentioned patch was applied, I noticed that
shutting down a kvm guest from inside (i.e. poweroff) caused
the guest to shutdown, but not removed from the list of
active guests. DanB pointed out that the problem is that
the virEventAddHandle() call in the qemu driver was asking
to watch for 0 events, not HANGUP | ERROR as it should. Add
these events so that shutdown works again.
