Kernel update: Virtuozzo ReadyKernel patch 57.0 for Virtuozzo 7.0.7 to 7.0.8¶

1. Overview¶

The cumulative Virtuozzo ReadyKernel patch was updated with a stability fix. The patch applies to kernels 3.10.0-693.17.1.vz7.43.10 (7.0.7), 3.10.0-693.21.1.vz7.46.7 (7.0.7 HF2), 3.10.0-693.21.1.vz7.48.2 (7.0.7 HF3), 3.10.0-862.9.1.vz7.63.3 (7.0.8).

2. Bug Fixes¶

• Kernel module ‘ip_set’ tried to allocate physically contiguous memory areas for its array of pointers to ‘ip_set’ structures in ip_set_net_init(). If large enough maximum number of IP sets was requested from the user space, memory allocation would fail. Containers would fail to start as a result. (PSBM-87338)

3. Installing the Update¶

Download, install, and immediately apply the patch to the current kernel by running ‘readykernel update’.
