New install fails on Linux Kernel check even though the version of the Linux kernel is above the minimum version from the install guide.
The QoreStor installer checks for specific versions of the Linux kernel:
3.10.0-514 3.10.0-693 3.10.0-862
This does not include the kernel that is in Red Hat 7.6 and CentOS 7.6.
The only resolution to this issue is to downgrade your version of Linux kernel, install QoreStor,

Development will always be moving to support newer kernels as they are released, but will always test before releasing.
