<quote> @item werror=@var{action},rerror=@var{action} Specify which @var{action} to take on write and read errors. Valid actions are: "ignore" (ignore the error and try to continue), "stop" (pause QEMU), "report" (report the error to the guest), "enospc" (pause QEMU only if the host disk is full; report the error to the guest otherwise). The default setting is @option{werror=enospc} and @option{rerror=report}. @item readonly </quote> libvirt doesn't set any default value for "(r)error_policy", the original doc should mean QEMU sets "report" as the default value for "werror", but it's not true, QEMU uses "enospc" as the default. And it's better to document "(r)error_policy" are only supported by QEMU. --- docs/formatdomain.html.in | 20 +++++++++----------- 1 files changed, 9 insertions(+), 11 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index dc6b152..e98e709 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1011,19 +1011,17 @@ The optional <code>error_policy</code> attribute controls how the hypervisor will behave on a disk read or write error, possible values are "stop", "report", "ignore", and - "enospace".<span class="since">Since 0.8.0, "report" since - 0.9.7</span> The default setting of error_policy is "report". - There is also an - optional <code>rerror_policy</code> that controls behavior - for read errors only. <span class="since">Since - 0.9.7</span>.
