Bug 2116718

Description of problem:
Attempting to allocate a cpu beyond the cpu range, the tuned command fails to run. But after restarting the virtual machine cmdline takes effect

Version-Release number of selected component (if applicable):
tuned version:
tuned-2.18.0-2.el9.noarch

kernel version:
5.14.0-142.rt21.142.el9.x86_64


How reproducible: 100%


Steps to Reproduce:
1. install tuned and tuned-profiles-nfv
2. isolate cpu1 and cpu2 on realtime-virtual-guest.conf
# lscpu -p
# The following is the parsable format, which can be fed to other
# programs. Each different item in every column has an unique ID
# starting usually from zero.
# CPU,Core,Socket,Node,,L1d,L1i,L2,L3
0,0,0,0,,0,0,0,0
1,1,1,0,,1,1,1,1
2,2,2,0,,2,2,2,2
# cat /etc/tuned/realtime-virtual-guest-variables.conf
isolated_cores=1,2
isolate_managed_irq=Y
# tuned-adm profile realtime-virtual-guest
# reboot
3. check isolation effect on cmdline
# cat /proc/cmdline
# cat /proc/cmdline 
BOOT_IMAGE=(hd0,msdos1)/vmlinuz-5.14.0-142.rt21.142.el9.x86_64 root=UUID=3f98037d-1d74-4076-a661-c4e1c651ba3e ro rhgb quiet crashkernel=1G-4G:192M,4G-64G

y=0 default_hugepagesz=1G hugepagesz=1G hugepages=4 intel_iommu=on iommu=pt panic_on_warn=1
4. change isolated_core to "1,2,3,4,5,6,7,8" on realtime-virtual-guest-variables.conf
# cat /etc/tuned/realtime-virtual-guest-variables.conf
isolated_cores=1,2,3,4,5,6,7,8
#isolated_cores=1,2
isolate_managed_irq=Y
# tuned-adm profile realtime-virtual-guest
Cannot load profile(s) 'realtime-virtual-guest': Assertion 'isolated_cores contains online CPU(s)' failed.
# reboot
5. check cmdline as below

# cat /proc/cmdline 
BOOT_IMAGE=(hd0,msdos1)/vmlinuz-5.14.0-142.rt21.142.el9.x86_64 root=UUID=3f98037d-1d74-4076-a661-c4e1c651ba3e ro rhgb quiet crashkernel=1G-4G:192M,4G-64G

No current active profile.

Actual results:
on step5, after guest reboot. Wrong cpu allocations appear in cmdline even though tuned profile is not running

Expected results:
if run "tuned-adm profile realtime-virtual-guest" failed, cmdline won't be changed.
