CloudLinux, a developer [ofhébergementdessystèmespartagésd'exploitation(OS), revealed that KernalCare supports Virtuozzo, making it easier to maintain high levels of security with updates in real time and ensure availability since no re-start is required.
with KernelCare, patches are made automatically as they become available, while the machine continues to run. KernelCare checks every four hours for updates to Parallels Virtuozzo Containers core and applies those necessary to prevent vulnerabilities. Patches solution loads with a module efficiency without impacting performance since the updates will take only nanoseconds.
For example, June 6 high vulnerability core became known (local privilege escalation vulnerability CVE-2014-3153) forcing administrators to scramble to re-starting servers in apart from the regular maintenance window. However, the next day, CloudLinux has released a patch - ahead of most distribution providers releasing new nuclei - so that KernelCare fixed the problem without involving administrators

KernelCare was first introduced there a month. CloudLinux claims to have sold more than 2,000 KernelCare licenses for hosting providers and companies use in their data centers.
"Taking the pain on the application of recent kernel security updates that come out every two months KernelCare is the perfect complement to Virtuozzo," said John Zanni, marketing manager, Parallels . "Live without patching the kernel re-start is a dream come true for administrators."
KernelCare is available via a monthly subscription. The kernel module is published under GPL2 while other components are distributed only licensed binary formats. KernelCare is now available for CentOS 6, Red Hat Enterprise Linux (RHEL) 6, CloudLinux OS 6 and OpenVZ (64-bit only). Over the next six weeks, CloudLinux plans to add support for RHEL 7. And in the next 60 days, it provides support for Debian and Ubuntu, and CentOS 5, RHEL 5, CloudLinux OS 5.
Founded in 09, CloudLinux has technical expertise in kernel development while its CloudLinux OS is used on more than 18,000 servers to increase server stability and security, bringing greater efficiency to providers Web hosting. The company is headquartered in Princeton, NJ, and its development based in Donetsk, Ukraine.
