Been hit with this too using locked down environments, (ie. ntp not allowed) and sycning to host's kernel using ptp_kvm had been highly succesful for all other Debian & RedHat based systems.... except Ubuntu ;(

BUT: this module is missing in the -kvm kernel or module flavored packages. It *IS* inside these packages: /lib/modules/5.4.0-1009-aws/kernel/drivers/ptp/ptp_kvm.ko linux-modules-extra-5.4.0-1009-aws /lib/modules/5.4.0-1009-gcp/kernel/drivers/ptp/ptp_kvm.ko linux-modules-extra-5.4.0-1009-gcp /lib/modules/5.4.0-1009-oracle/kernel/drivers/ptp/ptp_kvm.ko linux-modules-extra-5.4.0-1009-oracle /lib/modules/5.4.0-1010-azure/kernel/drivers/ptp/ptp_kvm.ko linux-modules-extra-5.4.0-1010-azure /lib/modules/5.4.0-26-generic/kernel/drivers/ptp/ptp_kvm.ko linux-modules-extra-5.4.0-26-generic /lib/modules/5.4.0-26-lowlatency/kernel/drivers/ptp/ptp_kvm.ko linux-modules-5.4.0-26-lowlatency /lib/modules/5.6.0-1007-oem/kernel/drivers/ptp/ptp_kvm.ko linux-modules-5.6.0-1007-oem For me it looks that the module should also in the linux-modules-*-kvm package which would make a lot sense.
