The following query can identify virtual machines that are waiting for Input/Output (I/O):

`kubevirt_vmi_vcpu_wait_seconds`::
Returns the wait time (in seconds) for a virtual machine's vCPU. Type: Counter.
`kubevirt_vmi_vcpu_wait_seconds_total`::
Returns the wait time (in seconds) on I/O for vCPUs of a virtual machine. Type: Counter.


A value above '0' means that the vCPU wants to run, but the host scheduler cannot run it yet. This inability to run indicates that there is an issue with I/O.

The following queries can identify which swap-enabled guests are performing the most memory swapping:

`kubevirt_vmi_memory_swap_in_traffic_bytes_total`::
`kubevirt_vmi_memory_swap_in_traffic_bytes`::
Returns the total amount (in bytes) of memory the virtual guest is swapping in. Type: Gauge.
