[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr
by Daniel P. Berrange 11 Jan '12

11 Jan '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> When sVirt is integrated with the LXC driver, it will be neccessary to invoke the security driver APIs using only a virDomainDefPtr since the lxc_container.c code has no virDomainObjPtr available. Aside from two functions which want obj->pid, every bit of the security driver code only touches obj->def. So we don't need to pass a virDomainObjPtr into the security drivers, a virDomainDefPtr is sufficient. Two functions also gain a 'pid_t pid' argument. * src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/security/security_apparmor.c, src/security/security_dac.c, src/security/security_driver.h, src/security/security_manager.c, src/security/security_manager.h, src/security/security_nop.c, src/security/security_selinux.c, src/security/security_stack.c: Change all security APIs to use a virDomainDefPtr instead of virDomainObjPtr --- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 28 ++-- src/qemu/qemu_migration.c | 12 +- src/qemu/qemu_process.c | 24 ++-- src/security/security_apparmor.c | 136 ++++++++++---------- src/security/security_dac.c | 91 +++++++------- src/security/security_driver.h | 36 +++--- src/security/security_manager.c | 40 +++--- src/security/security_manager.h | 36 +++--- src/security/security_nop.c | 36 +++--- src/security/security_selinux.c | 260 +++++++++++++++++++------------------- src/security/security_stack.c | 44 ++++--- 12 files changed, 381 insertions(+), 372 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6cfdd1d..6e001ce 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3096,7 +3096,7 @@ qemuDomainScreenshot(virDomainPtr dom, } unlink_tmp = true;

Let me try to understand it: is libvirt relying on an off tree API and we are now required to have stable guarantees to off tree APIs?

[libvirt] [PATCH] snapshot: allow reuse of existing files in disk snapshot
by Eric Blake 10 Jan '12

10 Jan '12

When disk snapshots were first implemented, libvirt blindly refused to allow an external snapshot destination that already exists, since qemu will blindly overwrite the contents of that file during the snapshot_blkdev monitor command, and we don't like a default of data loss by default. But VDSM has a scenario where NFS permissions are intentionally set so that the destination file can only be created by the management machine, and not the machine where the guest is running, so that libvirt will necessarily see the destination file already existing; adding a flag will allow VDSM to force the file reuse without libvirt complaining of possible data loss. https://bugzilla.redhat.com/show_bug.cgi?id=767104 * include/libvirt/libvirt.h.in (virDomainSnapshotCreateFlags): Add VIR_DOMAIN_SNAPSHOT_CREATE_REUSE_EXT. * src/libvirt.c (virDomainSnapshotCreateXML): Document it.

[libvirt] [PATCH 0/6] nwfilter: Enable access to variables via iterator or index
by Stefan Berger 10 Jan '12

10 Jan '12

This patch enables access to variables in filters using indep. iterators ($TEST[$@2]) or via index ($TEST[1]). Three test cases are added that are also being used for libvirt-TCK to check that the instantiation of the filtering rules is correct. Regards, Stefan

[libvirt] [PATCH] qemu: check for kvm availability before starting kvm guests
by Laine Stump 10 Jan '12

10 Jan '12

This *kind of* addresses: https://bugzilla.redhat.com/show_bug.cgi?id=772395 (it doesn't eliminate the failure to start, but causes libvirt to give a better idea about the cause of the failure). If a guest uses a kvm emulator (e.g. /usr/bin/qemu-kvm) and the guest is started when kvm isn't available (either because virtualization is unavailable / has been disabled in the BIOS, or the kvm modules haven't been loaded for some reason), a semi-cryptic error message is logged: libvirtError: internal error Child process (LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -device ? -device pci-assign,? -device virtio-blk-pci,? -device virtio-net-pci,?) status unexpected: exit status 1 This patch notices at process start that a guest needs kvm, and checks for the presence of /dev/kvm (a reasonable indicator that kvm is available) before trying to execute the qemu binary.
