We are pleased to announce the release of OSv 0.14 Alpha Release. Some of the noteworthy new features and improvements below.
We are proud to present OSv Dashboard The dashboard is a browser base UI pretension of the OSv and the virtual appliance status, visualizing the current system status in one place. Dashboard includes (among others):
- Main tab with Memory, CPU Disk chart
- Thread tab with interactive visualization of thread status and thread usage. You can select and search for particular thread by name.
- Trace tab, including a for each trace point frequency. Selection by name and search are available.
- JVM tab present basic JVM information like memory and GC, for the cases the Virtual Appliance is java base.
- Virtual Appliance tab present information relevant to the particular appliance. Tabs for Cassandra and Tomcat are currently available, with more too come.
- Swagger-UI for REST API interaction is still available, now as part of the bigger dashboard. To build the dashboard, just includes httpserver in the module list For example:
$ make -j 4 image=cassandra,httpserver
Once the appliance is running, the dashboard can be access via osv-ip:8000
We are continuously extending REST API coverage of OSv. Latest additions are:
-
Run API: new run API allows running an application after OSv has already started. The most common way to use a virtual appliance is to pre build it using Capstan or directly from source. However, in some cases, one would like to run an application after OSv already started. Possible use cases are:
- During the dev process, reducing the build/test cycle time
- When there is a configuration updates which must be done after OS is running, but before the application started
- Creating a generic OSv cloud image (e.g. EC2 AMI), uploading and run different application to it
-
Batch API: a "meta API", enabling a query/response of multiple REST API in one HTTP request. Useful in case one need to execute many query frequently, for example from the new OSv dashboard.
Full spec for latest API is available
Capstan now allow launching a Java application from the command line, with out the need of manually building a Capstanfile. Its as easy as:
$ capstan run target/capstan-example-java.jar
See example
More on setting SSL for the REST API (which the CLI usage) here
Some of the noteworthy additions are: initial support for device trees, including dynamic discovery of components (previously hard coded). This includes getting the physical memory information, OSv CLI, pl011 UART device, GIC interrupt controller, and the virtual timer.
- Zerocopy implementation for both Tx and Rx
- Set high priority on virtio-net's receive and transmit thread. What these two threads have in common is that each runs on a single CPU, but other CPUs can find themselves idle waiting for these threads to read new packets (or send old packets). To fully employ all available CPUs, it is important that both these threads run as soon as they can, regardless of which other thread happen to run on the same CPU. Setting both threads to high priority achieves that. This improve performance of a ycsb workload-C cassandra test on a KVM Guest with 4 vCPU by up to ~29% depend on the number of threads. Single vCPU results are desegregated by ~18% for the same use case.
Two of the most popular application development run time are now available on OSv:
Images of the new release are available at osv.io/downloads and using capstan search
EC2 community AMI are available here
