Q: Can I install the flexVDI packages in a virtual machine with CentOS/RHEL 7?
A: Short answer, no. Long answer, flexVDI is designed to be installed on a bare metal server, and the flexvdi-config tool will complaint about not finding virtualization extensions in the processor if it is run in a virtualized environment. Theoretically, you can overcome this problem if you activate nested virtualization in the outer hypervisor. However, this will come with an impact on performance and possibly other problems too. For this reason, nested virtualization is officially not supported, and you will not get any help by our support team for this configuration.
Q: What is the difference between persistent and volatile desktops?
A: A volatile desktop is a guest that can be deleted and replaced with a fresh one, and its user can keep working as if nothing happened. This is implemented in the following way:
A: Now flexVDI configuration defaults to not periodically rescan for new disk devices. After the disk is installed in the host, execute
servicesystemctl restart flexvdi-agent restart
And the flexVDI Host will update its device list without disturbing end users or virtual machines. The information will be automatically propagated to flexVDI manager and flexVDI dashboard in some seconds.
Q: The kernel shows a message like "KVM: vcpu0 disabled perfctr wrmsr". Is this a problem?
A: According to Red Hat, no, this warning message is of no concern. Just annoying.
