Failed to initialize dom0 state: No such device
Last modified: 2007-11-30 17:11:32 EST
Description of problem:
Xen doesn't work at all - xenstored shows:
FATAL: Failed to initialize dom0 state: No such device
full talloc report on 'null_context' (total 56 bytes in 3 blocks)
struct domain contains 56 bytes in 2 blocks (ref 0)
/local/domain/0 contains 16 bytes in 1 blocks (ref 0)
Because of this, xend doesn't correctly start.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install and update FC5
2. Boot into the Xen0 kernel
3. Start xend
4. Execute "xm list"
"xm list" cannot connect to xend.
"xm list" should return the list of Xen domains as usual
An strace of xenstored shows:
open("/proc/xen/xsd_kva", O_RDWR) = 10
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, 10, 0) = -1 ENODEV (No such
Downgrading to the 2.6.16-1.2096_FC5xen0 kernel fixes the problem.
