[libvirt] CfP VHPC20: HPC Containers-Kubernetes

==================================================================== CALL FOR PAPERSa 15th Workshop on Virtualization in High-Performance Cloud Computing (VHPC 20) held in conjunction with the International Supercomputing Conference - High Performance, June 21-25, 2020, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 25, 2020 Workshop URL: vhpc[dot]org Abstract registration Deadline: Jan 31st, 2020 Paper Submission Deadline: Apr 05th, 2020 Springer LNCS Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Most recently, Function as a Service (Faas) and Serverless computing, utilizing lightweight VMs-containers widens the spectrum of applications that can be deployed in a cloud environment, especially in an HPC context. Here, HPC-provided services can be become accessible to distributed workloads outside of large cluster environments. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

[libvirt] [PATCH] remote_daemon: Log host boot time
by Michal Privoznik 19 Dec '19

19 Dec '19

This is not strictly needed, but it makes sure we initialize the @bootTime global variable. Thing is, in order to validate XATTRs and prune those set in some previous runs of the host, a timestamp is recorded in XATTRs. The host boot time was unique enough so it was chosen as the timestamp value. And to avoid querying and parsing /proc/uptime every time, the query function does that only once and stores the boot time in a global variable. However, the only time the query function is called is in a child process that does lock files and changes seclabels. So effectively, we are doing exactly what we wanted to prevent from happening. The fix is simple, call the query function whilst the daemon is initializing. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- Since this will be used by security driver only, I was tempted to put this somewhere under src/security/, but especially because of split daemon I didn't. Placing this into remote_daemon.c makes sure all sub-daemons will have the variable initialized and won't suffer the problem. src/remote/remote_daemon.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/remote/remote_daemon.c b/src/remote/remote_daemon.c index b400b1dd10..5debb6ce97 100644 --- a/src/remote/remote_daemon.c +++ b/src/remote/remote_daemon.c @@ -57,6 +57,7 @@ #include "virgettext.h" #include "util/virnetdevopenvswitch.h" #include "virsystemd.h" +#include "virhostuptime.h" #include "driver.h" @@ -1020,6 +1021,7 @@ int main(int argc, char **argv) { bool implicit_conf = false; char *run_dir = NULL; mode_t old_umask; + unsigned long long bootTime; struct option opts[] = { { "verbose", no_argument, &verbose, 'v'}, @@ -1151,6 +1153,12 @@ int main(int argc, char **argv) { exit(EXIT_FAILURE); } + if (virHostGetBootTime(&bootTime) < 0) { + VIR_DEBUG("Unable to get host boot time"); + } else { + VIR_DEBUG("host boot time: %lld", bootTime); + } + daemonSetupNetDevOpenvswitch(config); if (daemonSetupAccessManager(config) < 0) { -- 2.24.1

[libvirt] [PATCH 1/1] qemu: hide details of fake reboot
by Nikolay Shirokovskiy 19 Dec '19

19 Dec '19

If we use fake reboot then domain goes thru running->shutdown->running state changes with shutdown state only for short period of time. At least this is implementation details leaking into API. And also there is one real case when this is not convinient. I'm doing a backup with the help of temporary block snapshot (with the help of qemu's API which is used in the newly created libvirt's backup API). If guest is shutdowned I want to continue to backup so I don't kill the process and domain is in shutdown state. Later when backup is finished I want to destroy qemu process. So I check if it is in shutdowned state and destroy it if it is. Now if instead of shutdown domain got fake reboot then I can destroy process in the middle of fake reboot process. After shutdown event we also get stop event and now as domain state is running it will be transitioned to paused state and back to running later. Though this is not critical for the described case I guess it is better not to leak these details to user too. So let's leave domain in running state on stop event if fake reboot is in process. As we don't know when stop event really arrive let's move resetting flag after starting CPUs - at this point stop event should be handled.
