Manao ahoana, Hello, Bonjour,
I would like to launch several KVM guests on a multicore CPU.
The number of the KVM process is over the number of physical cores.
I would like to limit each KVM process to say... 10% of CPU
I first use cpulimit
Would you know some better way to limit them? it's

Currently libvirt will turn on net.ipv4.ip_forward by writing 1\n to
/proc/sys/net/ipv4/ip_forward whenever a virtual network of with a
forward mode of nat or route is started. This is problematic for two
reasons: 1) /etc/sysctl.conf is not updated with this information, so

xenXMDomain*DeviceFlags() silently ignores requests to modify live
configuration of an active guest while still touching its persistent
configuration.

The following patch series introduces an attribute 'state' for iptables-
supported protocols. This gives the user more control over the 'state match'
of the underlying ip(6)tables implementation and allows to create filtering
rules that are more efficient to evaluate. TCK test cases will be posted
In this patch I am extending the rule instantiator to create the state
match according to the state attribute in the XML. Only one iptables
rule in the incoming or outgoing direction will be created for a rule
in direction 'in' or 'out' respectively. A rule in direction 'inout' does
get iptables
Extend the nwfilter.rng schema to accept state attributes.

This patch adds a test case for testing the XML parser's and instantiator's
support of the state attribute. The other test case tests existing
capabilities. Both test cases will be used in TCK again.
