[libvirt] [PATCH] configure: Fix check for --with-login-shell on Windows
by Andrea Bolognani 11 Apr '16

11 Apr '16

The check is supposed to stop users from trying to compile virt-login-shell on Windows by erroring out during the configure phase; however, there are two flaws in it: * the value of "x$with_win" is compared to "yes" instead of "xyes" (note the "x" in the first string) * "test" is not being used, so the script will actually try to run a command called "x$with_win" instead of performing string comparison This patch fixes both issues. --- m4/virt-login-shell.m4 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/m4/virt-login-shell.m4 b/m4/virt-login-shell.m4 index c77ffb5..d5e2e00 100644 --- a/m4/virt-login-shell.m4 +++ b/m4/virt-login-shell.m4 @@ -22,7 +22,7 @@ AC_DEFUN([LIBVIRT_CHECK_LOGIN_SHELL], [ if test "x$with_login_shell" != "xno"; then if test "x$with_win" = "xyes"; then - if "x$with_login_shell" = "yes"; then + if test "x$with_login_shell" = "xyes"; then AC_MSG_ERROR([virt-login-shell is not supported on Windows]) else with_login_shell=no; -- 2.5.5

[libvirt] [PATCH] po: Really fix po/POTFILES.in ordering
by Erik Skultety 10 Apr '16

10 Apr '16

Commit e72667bd tried to fix the incorrect file ordering in po/POTFILES.in except it didn't, since the sort was run using locale en_US instead of using locale C which is the default in libvirt.

[libvirt] [PATCH] po: fix POTFILES.in file ordering
by Erik Skultety 10 Apr '16

10 Apr '16

When it comes to a situation that a new translatable file needs to be added into the list of files, an automatically generated patch is proposed during syntax-check. However, the diff was made against a sorted list of files and the same sorted list of files + the new file that actually needs to be added into the list. Since we do not keep POTFILES sorted, the proposed patch thus can't be applied...most of the time - depending on the context.

[libvirt] Automatic Guest Resolution Adjustment not functional with GRsec guests
by bancfc＠openmailbox.org 10 Apr '16

10 Apr '16

A VM's QXL driver can no longer automatically adjust the screen resolution resize when running a GRsecurity kernel in the guest. The screen still responds to xrandr however but "scale display: always" in virt-manager doesn't work as it used to. What can be causing this?

[libvirt] [PATCH v2] Add macro for handling exponential backoff loops.
by Richard W.M. Jones 08 Apr '16

08 Apr '16

Since v1: - Rename the macro VIR_TIME_WHILE_WITH_BACKOFF. - Split out the variable initialization into a separate function that the user must call explicitly. - The macro is now an atomic C statement. An interesting observation about the qemu monitor socket: In some cases it appears almost instantaneously. In other runs it appears after 32-64ms. This latter case is what I expect because qemu startup takes ~50ms on my laptop. There seems to be no reason that I can discern for the difference between the runs. I've not observed the socket appearing anywhere in the middle, only at these two distinct time delays. Rich.
