Xen 4, не поднимается сеть

виснет, скорее всего, не от сети. сравните с моей конфигурацией

$ zgrep '^CONFIG.*XEN' /proc/config
CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_XEN_BALLOON=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XEN_BACKEND=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_XEN_XENBUS_FRONTEND=m
CONFIG_XEN_GNTDEV=m
CONFIG_XEN_GRANT_DEV_ALLOC=m
CONFIG_SWIOTLB_XEN=y
CONFIG_XEN_TMEM=y
CONFIG_XEN_PCIDEV_BACKEND=m

у меня работает на удивление стабильно (разумеется с учетом того, что это домашняя машина и домашние же нагрузки). конфигурация сети:

$ grep -v '^#' /etc/conf.d/net
dns_domain_lo="local"
config_eth0="null"
config_eth1="null"
slaves_bond0="eth0 eth1"
config_bond0="null"
bridge_add_bond0="xenbr"
config_xenbr="10.24.14.10/24 brd 10.24.14.255"
dns_domain_xenbr="local"
dns_servers_xenbr="10.24.14.12 10.24.14.32"
routes_xenbr="default via 10.24.14.32"
brctl_xenbr="stp off"

типа доказательства, что говорим об одном и том же :)
