Subject: KVM_GET_SUPPORTED_CPUID returning -E2BIG
Date: Sun, 08 May 2011 08:15:43 +0300 [thread overview]
Message-ID: <1304831743.10534.28.camel@lappy> (raw)
Hello,
I'm seeing a case where KVM tools occasionally fails with the following
error message: "KVM_GET_SUPPORTED_CPUID failed: Argument list too long",
which means that we get -E2BIG back from KVM_GET_SUPPORTED_CPUID.
Why would it happen if we pass KVM_MAX_CPUID_ENTRIES as the max number
of entries (in the nent field of struct kvm_cpuid2)?
Also, Why would it happen randomly and not each time the code is run?

Sasha.
