That depends on the .service files. This is the list of openSUSE Tumbleweed:

dev-hugepages.mount:ConditionVirtualization=!private-users
haveged.service:ConditionVirtualization=!container
hv_fcopy_daemon.service:ConditionVirtualization=microsoft
hv_kvp_daemon.service:ConditionVirtualization=microsoft
hv_vss_daemon.service:ConditionVirtualization=microsoft
irqd.service:ConditionVirtualization=!container
ksm.service:ConditionVirtualization=no
lxcfs.service:ConditionVirtualization=!container
mcelog.service:ConditionVirtualization=false
ntp-wait.service:ConditionVirtualization=!container
ntpd.service:ConditionVirtualization=!container
rng-tools.service:ConditionVirtualization=!container
smartd.service:ConditionVirtualization=false
sys-fs-fuse-connections.mount:ConditionVirtualization=!private-users
systemd-random-seed.service:ConditionVirtualization=!container
systemd-timesyncd.service:ConditionVirtualization=!container
vgauthd.service:ConditionVirtualization=vmware
vmblock-fuse.service:ConditionVirtualization=vmware
vmtoolsd.service:ConditionVirtualization=vmware
xendriverdomain.service:ConditionVirtualization=xen

I think the relevant services are ksm,mcelog and smartd. Each one likely
wants the "hardware domain" rather than the "toolstack domain". IMO what
systemd today sees as "dom0" should be set based on "XENFEAT_dom0".
