Error message reports that the guest has '0' NUMA nodes
configured when trying to attach a memory device to a guest with
no NUMA nodes. This may be a little misleading because '0' can
also be node's id. A more friendly way is to directly report
that the guest has no NUMA nodes.

The virNodeDeviceGetPCIVPDDynamicCap() function is called from
virNodeDeviceGetPCIDynamicCaps() and therefore has to be a wee
bit more clever about adding VPD capability. Namely, it has to
remove the old one before adding a new one. This is how other
functions called from virNodeDeviceGetPCIDynamicCaps() behave
as well.

When setting up QoS for a domain <interface/>, or when reporting
its statistics we may need to swap TX/RX values. This is all
explained in comment to virDomainNetTypeSharesHostView().
However, this function claims that VIR_DOMAIN_NET_TYPE_ETHERNET
also shares the 'host view', meaning the TX/RX values must be
swapped. But that's not true.
An easy reproducer is to start a domain with two <interface/>-s:
one type of network, the other of type ethernet and configure the
same <bandwidth/> for both. Reversed setting can then be observed
(e.g. via tc).

On aarch64 the 'id' file is not present for CPU cache information in
sysfs. This causes the local stateful hypervisor drivers to fail to
initialize capabilities:
virStateInitialize:657 : Initialisation of cloud-hypervisor state driver failed: no error
The 'no error' is because the 'virFileReadValueNNN' methods return
ret==-2, with no error raised, when the requeted file does not exist.
None of the callers were checking for this scenario when populating
capabilities. The most graceful way to handle this is to skip the
cache bank in question. This fixes failure to launch libvirt drivers
on certain aarch64 hardware.
