How many guests can I have on my KVM server?
In general, each KVM host supports up to 12 guest s. However, the limit is 8 guest s on servers that contain 384 GB of RAM and are configured to support Exadata Secure RDMA Fabric Isolation . Each guest is started alongside the KVM host. The guest s never interact with the KVM host directly.
Can a third party application be installed on a KVM host?
Oracle does not support any changes that are made to the KVM host beyond what is documented. Third-party applications can be installed on the KVM host and guest s, but if there are issues with the Oracle software, then Oracle Support Services may request the removal of the third-party software while troubleshooting the cause.
How to extend the guest space in Oracle KVM?
The KVM guest local space can be extended after initial deployment by adding local disk images. Use this procedure to expand /EXAVMIMAGES using available space on the KVM host . You can use Oracle Exadata Deployment Assistant (OEDA) to create a new Oracle Linux KVM cluster on an existing Oracle Exadata Database Machine.
How does SELinux pick the types of containers?
Container engines, like Podman and CRI-O, use the SELinux GO library to pick the types that will run with containers. Originally it read the /etc/selinux/targeted/contexts/lxc_contexts file. The library reads the process and file fields and sets the labels appropriately.
Why do we use SELinux in a kata container?
We use SELinux to prevent a rogue process inside a Kata container from taking advantage of a vulnerability in virtiofsd or qemu and using it to attack host content. Both qemu and virtiofsd require different access from what standard Linux containers are currently allowed. We could have extended the container_t type to add these additional accesses.
Can a KVM separated container read or write a file?
If a file has category s0:c3,c2, a container running with category s0:c1,c2 would not be able to read or write the files, since MCS says that a process categories have to dominate all categories in the file system object. Since each container runs with a unique pair of categories, no container can read or write another container’s data.
