[libvirt] [ PATCH v5 0/4] API to invoke S3/S4 on a host and also resume from within libvirt
by Srivatsa S. Bhat 29 Nov '11

29 Nov '11

This patchset adds a new API to put a host to a suspended state (Suspend-to-RAM, Suspend-to-Disk or Hybrid-Suspend) and setup a timed resume to get the host back online, from within libvirt. This uses the RTC wakeup mechanism to set up a timer alarm before suspending the host, so that in-band resume is facilitated by the firing of the RTC alarm, which wakes up the host. This patch applies on top of the Hybrid-Suspend patch posted in [1]. v5: * Added MIN_TIME_REQ_FOR_SUSPEND. * Incorporated the review comments in [3]. v4: * Applies on top of the Hybrid-Suspend patch posted in [1]. * Incorporated the review comments in [2]. v3: * Rebased to libvirt 0.9.7 * Added a check to see if alarmTime (suspend duration) is within an acceptable range. v2: * Added an init function which finds out if S3/S4 is supported by the host, upon the first request to suspend/hibernate. * Added synchronization/locking to ensure that only one suspend operation is active at a time. v1: http://www.redhat.com/archives/libvir-list/2011-September/msg00830.html v2: http://comments.gmane.org/gmane.comp.emulators.libvirt/46729 References: [1]. http://www.redhat.com/archives/libvir-list/2011-November/msg01407.html [2]. http://thread.gmane.org/gmane.comp.emulators.libvirt/47950 [3]. http://thread.gmane.org/gmane.comp.emulators.libvirt/49054 Srivatsa S.

[libvirt] [PATCH] Add 'Hybrid-Suspend' power management discovery for the host
by Srivatsa S. Bhat 29 Nov '11

29 Nov '11

Some systems support a feature known as 'Hybrid-Suspend', apart from the usual system-wide sleep states such as Suspend-to-RAM (S3) or Suspend-to-Disk (S4). Add the functionality to discover this power management feature and export it in the capabilities XML under the <power_management> tag. This addition was suggested in [1].

[libvirt] [RFC PATCH 0/5] Support online resizing of block devices.
by Osier Yang 28 Nov '11

28 Nov '11

This patch series introduce new API "virDomainBlockResize" to expose qemu monitor command "block_size", which is for resizing the a block device while the domain is running. The prototype for the new API is: int virDomainBlockResize (virDomainPtr dom, const char *path, unsigned long long size, unsigned int flags) * "@path" is the absolute path of the block device, which can be extraced from domain xml. * The units for "@size" is kilobytes, which might be not quite properly. (qemu HMP uses Megabytes as the default units, QMP uses Bytes as the default units, so it means we need to divice "@size" by 1024 for HMP, and multiply "@size" by 1024 for QMP. On the other hand, we need to check the overflowing). Any ideas on this is welcomed. * "@flags" is unused currently. [PATCH 1/5] block_resize: Define the new API [PATCH 2/5] block_resize: Wire up the remote protocol [PATCH 3/5] block_resize: Implement qemu monitor functions [PATCH 4/5] block_resize: Implement qemu driver method [PATCH 5/5] block_resize: Expose the new API to virsh

This patch series expands the streams APIs to allow practical use of non-blocking bi-directional streams. It also formally documents the required coding style conventions for libvirt-glib before we get too much more code that is out of the ordinary.

[libvirt] [ PATCH v4 0/4] API to invoke S3/S4 on a host and also resume from within libvirt
by Srivatsa S. Bhat 28 Nov '11

28 Nov '11

This patchset adds a new API to put a host to a suspended state (Suspend-to-RAM, Suspend-to-Disk or Hybrid-Suspend) and setup a timed resume to get the host back online, from within libvirt. This uses the RTC wakeup mechanism to set up a timer alarm before suspending the host, so that in-band resume is facilitated by the firing of the RTC alarm, which wakes up the host. The decision to use the RTC Wakeup mechanism to resume the host from sleep was taken in [1]. An initial API was discussed in [2]. Some design ideas for the asynchronous mechanism implementation was discussed in [3]. v4: * Applies on top of the Hybrid-Suspend patch posted in [4]. * Incorporated the review comments in [5]. v3: * Rebased to libvirt 0.9.7 * Added a check to see if alarmTime (suspend duration) is within an acceptable range. v2: * Added an init function which finds out if S3/S4 is supported by the host, upon the first request to suspend/hibernate. * Added synchronization/locking to ensure that only one suspend operation is active at a time. v1: http://www.redhat.com/archives/libvir-list/2011-September/msg00830.html v2: http://comments.gmane.org/gmane.comp.emulators.libvirt/46729 References: [1]. http://www.redhat.com/archives/libvir-list/2011-August/msg00327.html [2]. http://www.redhat.com/archives/libvir-list/2011-August/msg00248.html [3]. http://www.redhat.com/archives/libvir-list/2011-September/msg00438.html [4]. http://www.redhat.com/archives/libvir-list/2011-November/msg01407.html [5]. http://thread.gmane.org/gmane.comp.emulators.libvirt/47950 Srivatsa S.

[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr
by Daniel P. Berrange 28 Nov '11

28 Nov '11

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.

[libvirt] VBOX driver : "An error occurred, but the cause is unknown" when trying to start a Virtualbox domain
by Jean-Christophe Guillain 28 Nov '11

28 Nov '11

Hello, I opened a bug (http://bugzilla.redhat.com/show_bug.cgi?id=757138) about this issue, but I was told to mention it to this list too. Here is my problem : when I try to start a virtualbox domain with virsh, an error occurs. (But when the domain is started using Virtualbox GUI it works, and I have no problem to stop it with virsh...) Example : virsh # start freenas1 error: Failed to start domain freenas1 error: An error occurred, but the cause is unknown I use libvirt 0.9.2-7 and virtualbox 4.0.10 on a Debian with 2.6.32-5-amd64 kernel.

Malloc page than realloc to smaller does not work ?

Providing a posix_memalign_free defeats the purpose - POSIX requires that plain free() will cover the memory returned by posix_memalign. The list of platforms missing posix_memalign is a bit daunting: MacOS X 10.5, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, MSVC 9, Interix 3.5, BeOS. but what would be interesting to know is how many of those platforms return page-aligned pointers for any malloc() request of a page or more of memory. That is, we may be able to coerce malloc into aligned results by over-allocating and over-aligning the user's request, if the system malloc() has at least one mode of returning page-aligned memory. Another alternative is to override free() at the same time as providing posix_memalign(). The gnulib malloca module provides a freea() function that can distinguish whether it is paired with an alloca() (nop) or mmalloca() (call the real free()), by over-allocating and probing for a magic header. Similar concepts could be used in writing an rpl_free() that determines whether it was allocated by posix_memalign(): if we guarantee that posix_memalign always returns something aligned to at least a page, then rpl_free() can make a quick check for whether the pointer passed in is page-aligned; if so, do a hash lookup to see if it was a page reserved by our posix_memalign (if so, we know the real address to free); if not or the hash lookup fails, it came from malloc (in which case, regular free should work). Of course, unlike freea() that probes for a magic header, we can't safely probe a header by crossing page boundaries, since that would fault if we didn't allocate the previous page at the same time. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Not much but to be careful when you upgrade any part of libvirt, qemu(-kvm) or it's (external*) dependencies like etherboot/iPXE, vgabios and seabios, because it can invalidate your snapshots and saved state. (*): As Debian does for DFSG-compliance, since it replaces the seabios / vgabios / pxe-bios as shipped with qemu by a version compiled from (different) sources.

[libvirt] [PATCH 5/5] If a system has 64 or more VF's, it is quite tedious to mention each VF in the interface pool. The following modification find a Free VF given a Physical Function when mode=passthrough. We also save the state of each VF. Hence modifications to networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice were required. The following patch does just that.
